The Buddha describes the three kinds of misconduct - by body, speech and mind.

“There are three kinds of misconduct, bhikkhus. Which three? |Bodily misconduct::killing living beings, harming others, theft, or sexual misconduct [kāyaduccarita]|, |verbal misconduct::false speech, harsh speech, divisive speech, idle chatter [vacīduccarita]|, and |mental misconduct::yearning with strong eagerness and desire, having ill will or hatred, delighting in harm [manoduccarita]|. These, bhikkhus, are the three kinds of misconduct.”

Diligence should be practiced in four areas - in abandoning bodily, verbal, and mental misconduct, and wrong view.

1 Abandon |bodily misconduct::killing living beings, harming others, theft, or sexual misconduct [kāyaduccarita]| and develop good bodily conduct; do not be |negligent::inattentive, careless, intoxicated [pamāda]| in this.

The Buddha advises Tissa Metteyya on the dangers of engaging in sexual activity and the benefits of solitary conduct.

Thus the Venerable Tissa Metteyya said: “For one engaged in sexual activity, speak of the obstacles, dear sir; Having heard your teaching, we shall practice in solitude.”

Even if protected by an entire army, one who engages in misconduct is unprotected. But one who engages in good conduct protects themselves, even without external protection.

Then, venerable sir, it occurred to me: ‘Those who engage in |bodily misconduct::killing living beings, harming others, theft, or sexual misconduct [kāyaduccarita]|, |verbal misconduct::false speech, harsh speech, divisive speech, idle chatter [vacīduccarita]|, or |mental misconduct::yearning with strong eagerness and desire, having ill will or hatred, delighting in harm| leave themselves unprotected. Even though a company of elephant troops may protect them, or a company of cavalry, or a company of chariot troops, or a company of infantry, still they leave themselves unprotected. For what reason? Because that protection is external, not internal; therefore, they leave themselves unprotected.

The Buddha explains to the brahmin householders of Sālā the causes of rebirth in states of loss or in good destinations, emphasizing the importance of ethical and wholesome conduct. He outlines ten kinds of misconduct and ten kinds of wholesome conduct, illustrating how these actions lead to different outcomes after death.

Abandoning sexual misconduct, he refrains from sexual misconduct. He does not engage in sexual relations with those who are protected by their mother, protected by their father, protected by both parents, protected by their brother, protected by their sister, protected by their relatives, protected by a family clan, protected by religion, belonging to someone, who are under threat of punishment, or even those who are engaged to be married—he does not engage in such conduct. Thus, householders, there are three kinds of bodily conduct that are ethical and wholesome behaviors.

Beings come together and associate according to disposition. Those who kill living beings come together and associate with those who kill living beings; those who take what is not given come together and associate with those who take what is not given; and similar for the other three precepts.

“Bhikkhus, beings come together and associate |according to disposition::in line with their mental qualities or inclinations [dhātuso]|. Those |who kill living beings::who destroy life [pāṇātipātī]| come together and associate with those who kill living beings; those |who take what is not given::who steal [adinnādāyī]| come together and associate with those who take what is not given; those |who engage in sexual misconduct::who harm others through sexual activity [kāmesumicchācārī]| come together and associate with those who engage in sexual misconduct; those |who speak falsely::who lie [musāvādī]| come together and associate with those who speak falsely; those |who consume intoxicants::consuming wine, spirits, drugs and getting intoxicated [surāmerayamajjappamādaṭṭhāyī]| come together and associate with those who consume intoxicants.

BBeings come together and associate according to disposition. Those who speak divisively come together and associate with those who speak divisively; and six other associations are described.

“Bhikkhus, beings come together and associate |according to disposition::in line with their mental qualities or inclinations [dhātuso]|. Those |who kill living beings::who destroy life [pāṇātipātī]| come together and associate with those who kill living beings; those |who take what is not given::who steal [adinnādāyī]| come together and associate with those who take what is not given; those |who engage in sexual misconduct::who harm others through sexual activity [kāmesumicchācārī]| come together and associate with those who engage in sexual misconduct; those |who speak falsely::who lie [musāvādī]| come together and associate with those who speak falsely; those |who speak divisively::who separates others by speech, who sows discord [pisuṇavācā]| come together and associate with those who speak divisively; those |who speak harshly::who speak using rough words, rudely, or in an unkind manner [pharusavācā]| come together and associate with those who speak harshly; those |who chatter frivolously::who talk rubbish, who gossip [samphappalāpī]| come together and associate with those who chatter frivolously.

The Noble Eightfold Path is the path and the way of practice for the realization of awakening.

“Friend, this Noble Eightfold Path itself is the way to realize awakening, namely — |right view::view that is in line with the Dhamma - teachings of the Buddha that point to the nature of reality, the ultimate truth [sammādiṭṭhi]|, |right intention::intention of renunciation, goodwill, and harmlessness; the resolve to let go of craving, ill will, and cruelty, cultivating thoughts that lead to peace and liberation [sammāsaṅkappa]|, |right speech::speech that is truthful, harmonious, gentle, and meaningful; abstaining from false speech, divisive speech, harsh speech, and idle chatter [sammāvācā]|, |right action::action that upholds ethical integrity by abstaining from killing, stealing, and sexual misconduct; bodily conduct aligned with harmlessness and honesty [sammākammanta]|, |right livelihood::means of living that does not cause harm to others or oneself; earning a living ethically without deceit, exploitation, or violence [sammāājīva]|, |right effort::energy and effort directed toward abandoning unwholesome mental states and qualities, and cultivating wholesome ones [sammāvāyāma]|, |right mindfulness::mindfulness that discerns the body, feelings, mind, and mental qualities clearly, grounded in diligent, non-forgetful attention to the present moment [sammāsati]|, and |right collectedness::perfect stability of mind, correct mental composure [sammāsamādhi]|. This, friend, is the path; this is the way of practice for the realization of awakening.”

Beings come together and associate according to disposition. Those who intense craving come together and associate with those with intense craving; those with a malicious mind come together and associate with those with a malicious mind; those with wrong views come together and associate with those with wrong views; and similar for the other seven kinds of actions.

“Bhikkhus, beings come together and associate |according to disposition::in line with their mental qualities or inclinations [dhātuso]|. Those |who kill living beings::who destroy life [pāṇātipātī]| come together and associate with those who kill living beings; those |who take what is not given::who steal [adinnādāyī]| come together and associate with those who take what is not given; those |who engage in sexual misconduct::who harm others through sexual activity [kāmesumicchācārī]| come together and associate with those who engage in sexual misconduct; those |who speak falsely::who lie [musāvādī]| come together and associate with those who speak falsely; those |who speak divisively::who separates others by speech, who sows discord [pisuṇavācā]| come together and associate with those who speak divisively; those |who speak harshly::who speak using rough words, rudely, or in an unkind manner [pharusavācā]| come together and associate with those who speak harshly; those |who chatter frivolously::who talk rubbish, who gossip [samphappalāpī]| come together and associate with those who chatter frivolously; those |with intense craving::who are greedy, covetous, yearning, desiring, mentally obsessed [abhijjhālu]| come together and associate with those with intense craving; those |with a malicious mind::who are hateful, who have a mind full of ill will [byāpannacittā]| come together and associate with those who with a malicious mind; those |with wrong views::with false beliefs, false concepts, incorrect opinions [micchādiṭṭhika]| come together and associate with those with wrong views.

The Noble Eightfold Path is the path and the way for the realization of Nibbāna.

“Friend, this Noble Eightfold Path itself is the way for the realization of this Nibbāna, namely — |right view::view that is in line with the Dhamma - teachings of the Buddha that point to the nature of reality, the ultimate truth [sammādiṭṭhi]|, |right intention::intention of renunciation, goodwill, and harmlessness; the resolve to let go of craving, ill will, and cruelty, cultivating thoughts that lead to peace and liberation [sammāsaṅkappa]|, |right speech::speech that is truthful, harmonious, gentle, and meaningful; abstaining from false speech, divisive speech, harsh speech, and idle chatter [sammāvācā]|, |right action::action that upholds ethical integrity by abstaining from killing, stealing, and sexual misconduct; bodily conduct aligned with harmlessness and honesty [sammākammanta]|, |right livelihood::means of living that does not cause harm to others or oneself; earning a living ethically without deceit, exploitation, or violence [sammāājīva]|, |right effort::energy and effort directed toward abandoning unwholesome mental states and qualities, and cultivating wholesome ones [sammāvāyāma]|, |right mindfulness::mindfulness that discerns the body, feelings, mind, and mental qualities clearly, grounded in diligent, non-forgetful attention to the present moment [sammāsati]|, and |right collectedness::perfect stability of mind, correct mental composure [sammāsamādhi]|. This, friend, is the path, this is the way for the realization of this Nibbāna.”

Dhammapada verses 221-234 emphasize abandoning anger, conceit, and mental defilements while cultivating restraint in body, speech, and mind. The verses highlight overcoming harmful actions by giving and speaking truth, the inevitability of criticism, and the value of moral discipline. Those intent on Nibbāna, ever watchful, and well-restrained are beyond reproach and honored even by the gods.

One should guard against |irritability in bodily action::harmful bodily behavior, physical agitation [kāyappakopa]|, be restrained in bodily actions; Having abandoned |bodily misconduct::killing living beings, harming others, theft, or sexual misconduct [kāyaduccarita]|, one should practice good bodily conduct.

The Buddha describes the seven kinds of wealth in detail, of 1) faith, 2) virtue, 3) conscience, 4) fear of wrongdoing, 5) learning, 6) generosity, and 7) wisdom. One who possesses these is not truly poor, and their life is not lived in vain.

And what, bhikkhus, is the wealth of |conscience::internal sense of right and wrong used for guiding one’s behavior, moral shame, scruple [hirī]|? Here, bhikkhus, a disciple of the Noble Ones possesses moral conscience; he is ashamed of bodily misconduct, verbal misconduct, and mental misconduct, and is ashamed of acquiring |harmful::injurious, destructive, bad, or evil [pāpaka]|, unwholesome states. This is called the wealth of conscience.

Three kinds of children - 1) one who surpasses their parents, 2) one who follows in their footsteps, and 3) one who falls below them.

And how, bhikkhus, does a child become one who surpasses their parents? Here, bhikkhus, a child’s parents are ones who have not gone to the Buddha, |Dhamma::teachings of the Buddha that point to the nature of reality, the ultimate truth [dhamma]|, or |Saṅgha::The community of monks and nuns practicing in line with the Buddha’s teachings. In the broader sense, this is the community of disciples who have realized the noble path and fruition through the Buddha’s teachings [saṅgha]| for refuge. They do not abstain from killing living beings, from taking what is not given, from sexual misconduct, from false speech, and from |consuming intoxicants::consuming wine, spirits, or drugs and getting intoxicated [surāmerayamajjappamādaṭṭhāyī]| causing carelessness; they are |unprincipled::without regard for ethical conduct [dussīla]| and |endowed with harmful qualities::one who has had a long association of harmful mental qualities - of negligence, laziness, having many wishes, irrational application of mind, lack of situational awareness, having bad friends, pursuing bad habits [pāpadhamma]|. But their child has gone to the Buddha, Dhamma, and Saṅgha for refuge. They refrain from killing living beings, from taking what is not given, from sexual misconduct, from false speech, and from consuming intoxicants causing carelessness. They are |virtuous::ethical, moral [sīlavant]| and |endowed with wholesome qualities::one who has had a long association of wholesome mental qualities - of diligence, aroused energy, having few wishes, rational application of mind, having situational awareness, having good friends, pursuing good habits [kalyāṇadhamma]|. In this way, bhikkhus, a child becomes one who surpasses their parents.

Dhammapada verses 129-145 explore the themes of non-violence, the consequences of harmful actions, and the importance of self-discipline. Through metaphors of a broken gong, a well-trained horse, and skilled artisans, the verses emphasize that true purification comes not from external austerities but from inner restraint, mindfulness, and ethical conduct. The inevitability of death and the suffering caused by harming others are highlighted alongside the rewards of peace and wisdom for those who cultivate virtuous behavior.

Even if adorned, if one walks |with tranquility::with balance, with serenity [sama]|, At peace, tamed, restrained, and |practicing the spiritual life::living the spiritual life, abstaining from sexual intercourse [brahmacāri]|; Having laid down |violence::actions that cause injury [daṇḍa]| towards all beings, that person is a brahmin, an ascetic, a bhikkhu.

Using the simile of an elephant’s footprint, the Buddha illustrates how confidence in him develops gradually through practice. A noble disciple trains in conduct, sense restraint, contentment, and mindfulness, progressing through the jhānas. Unshakable confidence in the Buddha, Dhamma, and Saṅgha arises through direct knowledge and liberation.

He abandons unchastity and observes celibacy, living apart, and refrains from |sexual activity::sexual intercourse [methuna]|, the common person’s practice.

The Buddha explains in detail each factor of the noble eightfold path—right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right collectedness.

And what, bhikkhus, is right action? That which, bhikkhus, is abstention from |killing living beings::taking life, destruction of life [pāṇātipāta]|, abstention from |taking what is not given::theft, stealing, taking what is not offered [adinnādāna]|, abstention from |sexual misconduct::unchastity [abrahmacariya]|—this is called right action, bhikkhus.

The Buddha explains the four qualities that lead to the benefit and happiness in this life and in the future life.

2 And what, Byagghapajja, is |accomplishment of ethical conduct::attainment of virtue [sīlasampadā]|? Here, Byagghapajja, a son of a good family refrains from killing living beings, refrains from taking what is not given, refrains from sexual misconduct, refrains from false speech, and refrains from |intoxicants::liquor, wine, spirits, drugs, caffeine; substances that promote dwelling without regard for diligence| that cause |negligence::not having regard for diligence, carelessness, heedlessness [pamāda]|. This, Byagghapajja, is called accomplishment of ethical conduct.

The Buddha uses the gradual purification of gold as a metaphor for mental cultivation through meditation. Just as a goldsmith removes coarse, medium, and subtle impurities until the gold is workable and radiant, a meditator abandons defilements in stages. This gradual refinement leads to deep collectedness of mind, forming the foundation for supernormal abilities and, ultimately, liberation.

“So too, bhikkhus, for a bhikkhu devoted to the higher mind, there are coarse defilements: |bodily misconduct::killing living beings, harming others, theft, or sexual misconduct [kāyaduccarita]|, |verbal misconduct::false speech, harsh speech, divisive speech, idle chatter [vacīduccarita]|, and |mental misconduct::yearning with strong eagerness and desire, having ill will or hatred, delighting in harm|. An attentive and capable bhikkhu abandons these, dispels them, eliminates them, and brings them to nought.

The Buddha explains how one can verify that they are a stream-enterer by reflecting on the five perilous animosities, the four factors of stream-entry, and clearly seeing with wisdom the noble principle of dependent co-arising.

3 Householder, |one who engages in sexual misconduct::one who engages in adultery or behaves wrongly [kāmesumicchācārī]|, dependent on engaging in sexual misconduct, generates peril and animosity concerning this life, peril and animosity concerning the next life, and they personally experience suffering and mental distress. But for one who has abstained from sexual misconduct, that peril and animosity has subsided.

The venerable Nandaka teaches Sāḷha and his friend about how to independently verify the unwholesome and wholesome mental qualities.

“I declare that this means |yearning for with strong eagerness and desire::wishing for, wanting, longing for, insatiability [abhijjhati]|. Indeed, an insatiable person, being greedy, might kill living beings, take what is not given, engage in sexual misconduct, lie, and persuade others to do likewise, which results in long-term harm and suffering.”

The Buddha describes the three divine messengers that appear among human beings and what happens to those who do not heed their message.

“Here, bhikkhus, a certain person engages in |bodily misconduct::killing living beings, harming others, theft, or sexual misconduct [kāyaduccarita]|, |verbal misconduct::false speech, harsh speech, divisive speech, idle chatter [vacīduccarita]|, and |mental misconduct::yearning with strong eagerness and desire, having ill will or hatred, delighting in harm [manoduccarita]|. Having engaged in misconduct by way of body, speech, and mind, after the breaking up of the body at death, they are |reborn in a state of loss::in a state of misery [apāya]|, in a bad destination, in the |realms of downfall::in realms of misery [vinipāta]|, in |hell::a place of intense suffering, lit. no good fortune [niraya]|. Bhikkhus, then the hell wardens seize that person by both arms and present them to |King Yama::lord of the underworld, who acts as a moral examiner and questions the recently deceased about their failure to heed the divine messengers—aging, illness, and death. He reminds beings that they alone are responsible for their past deeds [yama]|, saying: ‘This man, your majesty, did not respect their mother, did not respect their father, did not respect ascetics, did not respect the |Brahmans::a title used by the Buddha for an Arahant, an awakened being [brahmañña]|, and did not respect the elders in their family. May your majesty impose due punishment on him.’

Short teachings on the impossibility of certain events, actions, or outcomes.

“It is impossible, bhikkhus, it is inconceivable that a wished for, desirable, or agreeable result could be produced from |bodily misconduct::killing living beings, harming others, theft, or sexual misconduct [kāyaduccarita]|. Such a possibility does not exist. But it is possible, bhikkhus, that an unwished for, undesirable, or disagreeable result could be produced from bodily misconduct. Such a possibility does exist.”

Venerable Ānanda recollects the wonderful and marvelous qualities of the Tathāgata, the Buddha, relating to his conception and birth. The Buddha then caps it off by sharing what he considers the most wonderful and marvelous quality of all.

I heard and learned this, venerable sir, from the Blessed One’s own lips: ‘When, Ānanda, the Bodhisatta had descended into his mother’s womb, she became intrinsically virtuous, abstaining from killing living beings, from taking what is not given, from misconduct in sensual pleasures, from false speech, and from |intoxicants::liquor, wine, spirits, drugs, caffeine; substances that promote dwelling without regard for diligence|’—this too I remember as a wonderful and marvelous quality of the Blessed One.

The Buddha expounds the noble right collectedness complete with its supporting conditions, clarifying how the factors of the noble eightfold path give rise to either mundane or supramundane fruits. He shows how right view leads to the sequential development of the path, culminating in right knowledge and right liberation.

And what, bhikkhus, is wrong action? |Killing living beings::taking life, destruction of life [pāṇātipāta]|, |taking what is not given::theft, stealing, taking what is not offered [adinnādāna]|, |sexual misconduct::misbehavior in matters of sensuality, wrong sexual behavior [kāmesumicchācāra]|—this is wrong action.

The Buddha affirms the Four Noble Truths as the core of his teaching and praises venerable Sāriputta’s deep understanding of them, who then expounds the truths, detailing suffering in all its forms, the arising of suffering rooted in craving, the ending of suffering, and the Noble Eightfold Path as the way of practice leading to the end suffering.

And what, friends, is right action? Abstention from |killing living beings::taking life, destruction of life [pāṇātipāta]|, abstention from |taking what is not given::theft, stealing, taking what is not offered [adinnādāna]|, abstention from |sexual misconduct::unchastity [abrahmacariya]| — this, friends, is called right action.

The Buddha explains the three bases of sectarian views that when closely examined, culminate in inaction. He then shares the Dhamma that is irrefutable, undefiled, blameless, and not disapproved of by the wise.

1 Bhikkhus, I approached those ascetics and brahmins who hold such a doctrine and view as this: ‘Whatever this person experiences—whether pleasure, pain, or neither-pleasure-nor-pain—all that is due to what was done in the past,’ and I said to them: “Is it true, venerable sirs, that you hold such a doctrine and view as this: “Whatever this person experiences—whether pleasure, pain, or neither-pleasure-nor-pain—all that is due to what was done in the past?" And when questioned in this way, they acknowledge it, saying: ‘Yes.’ Then I say to them: ‘In that case, venerable sirs, you must also say that those |who kill living beings::who destroy life [pāṇātipātī]| do so due to what was done in the past, those |who take what is not given::who steal [adinnādāyī]| do so due to what was done in the past, those |who engage in sexual misconduct::who harm others through sexual activity [kāmesumicchācārī]| do so due to what was done in the past, those |who speak falsely::who lie [musāvādī]| do so due to what was done in the past, those who speak divisively do so due to what was done in the past, those |who speak harshly::who speak using rough words, rudely, or in an unkind manner [pharusavācā]| do so due to what was done in the past, those |who chatter frivolously::who talk rubbish, who gossip [samphappalāpī]| do so due to what was done in the past, those who |have intense craving::be greedy, covetous, with yearning, desiring, mentally obsessed [abhijjhālu]| have it due to what was done in the past, those |with a malicious mind::evil-minded, hateful [byāpannacitta]| are so due to what was done in the past, and those |with wrong views::with false beliefs, false concepts, incorrect opinions [micchādiṭṭhika]| are so due to what was done in the past.’

The Buddha describes the wholesome and unwholesome states to the wanderer Vacchagotta, and then answers Vacchagotta’s questions about the accomplishments of his disciples.

Killing living beings, Vaccha, is unwholesome; abstaining from killing living beings is wholesome. Taking what is not given, Vaccha, is unwholesome; abstaining from taking what is not given is wholesome. Sexual misconduct, Vaccha, is unwholesome; abstaining from sexual misconduct is wholesome. False speech, Vaccha, is unwholesome; abstaining from false speech is wholesome. Malicious speech, Vaccha, is unwholesome; abstaining from malicious speech is wholesome. Harsh speech, Vaccha, is unwholesome; abstaining from harsh speech is wholesome. Idle chatter, Vaccha, is unwholesome; abstaining from idle chatter is wholesome. Craving, Vaccha, is unwholesome; contentment is wholesome. Ill will, Vaccha, is unwholesome; non-ill will is wholesome. Wrong view, Vaccha, is unwholesome; right view is wholesome. Thus, Vaccha, these ten qualities are unwholesome, and these ten qualities are wholesome.

Prompted by a misquotation of the Buddha regarding mental versus physical and verbal actions, the Buddha clarifies the nature of kamma and its results. He explains, through a framework of four paradoxical cases, how actions may lead to unexpected outcomes based on prior deeds or conditions at death.

Here, Ānanda, a certain ascetic or brahmin, through application, exertion, inquiry, |diligence::quality of wishing to do one’s work or duty well, with alertness, carefulness and care [appamāda]|, and right attention, attains such a |stability of mind::stillness of mind, mental composure [cetosamādhi]| that, when his mind is thus collected, with the |divine eye::the faculty of clairvoyance, the ability to see beyond the ordinary human range [dibbacakkhu]|, purified and surpassing the human, he sees that person—one who kills living beings, takes what is not given, engages in sexual misconduct, speaks falsely, speaks divisively, speaks harshly, chatters frivolously, has intense craving, is with a malicious mind, and holds wrong view—with the breakup of the body, after death, he sees him reborn in a state of loss, in a bad destination, in the realms of downfall, in hell. He says thus: ‘Inaction, sir, there are |harmful::injurious, destructive, bad, or evil [pāpaka]| actions; there is the result of misconduct. I have seen that person—one who kills living beings, takes what is not given… holds wrong view—and I see him, with the breakup of the body, after death, reborn in a state of loss, in a bad destination, in the realms of downfall, in hell.’ And he says thus: ‘Whoever, sir, kills living beings, takes what is not given… holds wrong view—every one of them, with the breakup of the body, after death, is reborn in a state of loss, in a bad destination, in realms of downfall, in hell. Those who know thus, know rightly; those who think otherwise, their knowledge is false.’ Thus, whatever he has personally known, personally seen, personally understood—this alone he clings to stubbornly, doubling down, and insisting: ‘Only this is true, anything else is wrong.’

The Buddha explains the fruit, benefit, brightness, and reach of observing the Uposatha endowed with the eight factors in detail.

3 ‘For as long as they live, the arahants, having abandoned unchastity, are celibate, living apart, and refrain from |sexual activity::sexual intercourse [methuna]|, the common person’s practice. Today, for this night and day, I too, having abandoned unchastity, will be celibate, living apart, and will refrain from sexual activity, the common person’s practice. In this way, I shall follow the example of the arahants, and the Uposatha will be observed by me.’ Thus, one is endowed with the third factor.

Venerable Sāriputta gives a detailed explanation of right view, the first factor of the noble eightfold path. At the prompting of the other bhikkhus, he approaches the topic from a wide range of perspectives.

What, friends, is the unwholesome, what is the root of the unwholesome, what is the wholesome, what is the root of the wholesome? Taking life, friends, is unwholesome; taking what is not given, engaging in sexual misconduct, lying, divisive speech, harsh speech, idle chatter, covetousness, ill will, and wrong view — this, friends, is called unwholesome.
