In The Path of Dhamma (Dhammapada)
Dhammapada verses 306–319 warn of the suffering that follows false speech, misconduct, and wrong view. The verses highlight the danger of negligence, hypocrisy, and slack effort in spiritual practice. Those who cultivate right view, ethical conduct, and firm effort attain a good destination, while those who embrace wrong views and harmful actions fall into misery.
In As It Was Said (Itivuttaka)
A person who is lacking continuous effort and is without concern is incapable of attaining full awakening, Nibbāna, and the unsurpassed safety from bondage.
The Buddha describes two types of bhikkhus based on how they deal with thoughts of sensuality, ill will, and harming while walking, standing, sitting, and lying down, and which one is capable of reaching the highest awakening.
In Middle Length Discourses (Majjhima Nikāya)
The Buddha explains to the brahmin Jāṇussoṇi how he overcame fright and dread while practicing seclusion in remote lodgings in the forests and woodlands, leading to the three true knowledges and full awakening.
The Buddha distinguishes pleasant abidings in the here and now from the way of effacement leading upwards to complete quenching. Effacement is shown as the gradual chipping away of defilements through restraint, cultivation of the noble eightfold path, and diligent training, culminating in the complete freedom of Nibbāna.
