The Buddha explains to a brahmin that the cycle of existence is without a discoverable beginning, and that it is not easy to calculate the number of aeons that have passed by and gone.

SN 15.8  Gaṅgā sutta - Ganges

Rājagahe viharati veḷuvane. Atha kho aññataro brāhmaṇo yena bhagavā tenupasaṅkami; upasaṅkamitvā bhagavatā saddhiṁ sammodi.

At one time, the Blessed One was dwelling at |Rājagaha::name of a city; capital of Magadha; lit. king’s house [rājagaha]|, in the Bamboo Grove. Then a certain brahmin approached the Blessed One, and having approached, he exchanged greetings with him.

Sammodanīyaṁ kathaṁ sāraṇīyaṁ vītisāretvā ekamantaṁ nisīdi. Ekamantaṁ nisinno kho so brāhmaṇo bhagavantaṁ etadavoca: “kīvabahukā nu kho, bho gotama, kappā abbhatītā atikkantā”ti?

After the exchange of courteous and polite conversation, he sat down to one side. Seated to one side, the brahmin addressed the Blessed One: “Venerable Gotama, how many aeons have passed by and gone?”

“Bahukā kho, brāhmaṇa, kappā abbhatītā atikkantā. Te na sukarā saṅkhātuṁ: ‘ettakā kappā iti vā, ettakāni kappasatāni iti vā, ettakāni kappasahassāni iti vā, ettakāni kappasatasahassāni iti vā’”ti.

Truly, brahmin, many aeons have passed by and gone. They are not easy to calculate—whether as ‘so many aeons,’ ‘so many hundreds of aeons,’ ‘so many thousands of aeons,’ or even ‘so many hundreds of thousands of aeons.

“Sakkā pana, bho gotama, upamaṁ kātun”ti?

“But, venerable Gotama, is it possible to offer a |simile::comparison, illustrative example [upamā]|?”

“Sakkā, brāhmaṇā”ti bhagavā avoca.

“It is possible, brahmin,” the Blessed One replied.

“Seyyathāpi, brāhmaṇa, yato cāyaṁ gaṅgā nadī pabhavati yattha ca mahāsamuddaṁ appeti, etasmiṁ antare vālikā na sukarā saṅkhātuṁ: ‘ettakā vālikā iti vā, ettakāni vālikasatāni iti vā, ettakāni vālikasahassāni iti vā, ettakāni vālikasatasahassāni iti vā’ti. Tato bahutarā kho, brāhmaṇa, kappā abbhatītā atikkantā. Te na sukarā saṅkhātuṁ: ‘ettakā kappā iti vā, ettakāni kappasatāni iti vā, ettakāni kappasahassāni iti vā, ettakāni kappasatasahassāni iti vā’ti.

“Just like, brahmin, from where this |Ganges::one of the five great rivers of ancient India [gaṅgā]| river springs up and flows into the great ocean, whatever sand lies within this space is not easy to calculate—whether as ‘so many grains of sand,’ ‘so many hundreds of grains of sand,’ ‘so many thousands of grains of sand,’ or even ‘so many hundreds of thousands of grains of sand.’ Even more numerous than that, brahmin, are the aeons that have passed by and gone. They are not easy to calculate—whether as ‘so many aeons,’ ‘so many hundreds of aeons,’ ‘so many thousands of aeons,’ or even ‘so many hundreds of thousands of aeons.’

Taṁ kissa hetu? Anamataggoyaṁ, brāhmaṇa, saṁsāro. Pubbā koṭi na paññāyati avijjānīvaraṇānaṁ sattānaṁ taṇhāsaṁyojanānaṁ sandhāvataṁ saṁsarataṁ. Evaṁ dīgharattaṁ kho, brāhmaṇa, dukkhaṁ paccanubhūtaṁ tibbaṁ paccanubhūtaṁ byasanaṁ paccanubhūtaṁ, kaṭasī vaḍḍhitā. Yāvañcidaṁ, brāhmaṇa, alameva sabbasaṅkhāresu nibbindituṁ, alaṁ virajjituṁ, alaṁ vimuccitun”ti.

Why is that? This |cyclic existence::the continuous cycle of birth, death, and rebirth [saṁsāra]|, brahmin, is without a discoverable beginning. A first point is not evident of beings who, obstructed by |ignorance::fundamental unawareness or misunderstanding of the true nature of reality, not experientially understanding the four noble truths [avijjā]| and fettered by |craving::wanting, yearning, longing, attachment, lit. thirst [taṇha]|, run on and wander in this cycle of existence. For a long time, brahmin, you have experienced |suffering::discomfort, unpleasantness, discontentment, dissatisfaction, stress, pain, disease, i.e. mild or intense suffering [dukkha]|, |agony::intense suffering, anguish [tibba]|, and |calamity::disaster [byasana]|, the |cemetery::charnel ground [kaṭasī]| has been filled up with your bones. Therefore, brahmin, it is enough |to become disenchanted::to become disillusioned [nibbindituṃ]|, |to become detached::to become dispassionate [virajjituṁ]| and |to become free from::to be liberated from [vimuccituṃ]| |all conditions::all formations, all activities, all fabrications [sabbasaṅkhāra]|.”

Evaṁ vutte, so brāhmaṇo bhagavantaṁ etadavoca: “Abhikkantaṁ, bho gotama, abhikkantaṁ, bho gotama. Seyyathāpi, bho gotama, nikkujjitaṁ ukkujjeyya, paṭicchannaṁ vivareyya, mūḷhassa maggaṁ ācikkheyya, andhakāre telapajjotaṁ dhāreyya: ‘cakkhumanto rūpāni dakkhantī’ti; evamevaṁ bhotā gotamena anekapariyāyena dhammo pakāsito. Esāhaṁ bhavantaṁ gotamaṁ saraṇaṁ gacchāmi dhammañca bhikkhusaṅghañca. Upāsakaṁ maṁ bhavaṁ gotamo dhāretu ajjatagge pāṇupetaṁ saraṇaṁ gatan”ti.

When this was said, that brahmin said to the Blessed One: “Excellent, venerable Gotama! Excellent, venerable Gotama! Just as if one might set upright what had been overturned, |reveal::uncover [vivarati]| what had been concealed, point out the way to one who was lost, or hold up a lamp in the dark so that those with eyes could see forms, in the same way, venerable Gotama, the |Dhamma::teachings of the Buddha that point to the nature of reality, the ultimate truth [dhamma]| has been |explained::illustrated [pakāsita]| by you in many ways. I go for refuge to venerable Gotama, to the Dhamma, and to the |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]| of bhikkhus. May sir Gotama remember me as a |lay disciple::one who takes refuge in the Buddha, Dhamma, and Saṅgha [upāsaka]| who, from this day forward, has gone to refuge for life.

Qualities:

Craving

A driving ‘thirst’ that reaches out toward experiences, identities, or outcomes as the place to find satisfaction—“if only I had that.” It spins stories of lack, binds the mind to becoming, and invariably leads to suffering.

Also known as: wanting, yearning, longing, lit. thirst

Ignorance

Ignorance

A fundamental blindness to the true nature of reality. It is not merely a lack of information, but an active misperception that views the transient as permanent and the unsatisfactory as a source of happiness, thereby fueling the cycle of suffering.

Also known as: illusion of knowing, fundamental unawareness of the true nature of reality, misunderstanding of how things have come to be, not knowing the four noble truths
