The Buddha uses the simile of a defiled cloth to explain how the mind can be similarly defiled by various impurities, and how it can be purified by abandoning them. And it is through this very practice that one arrives at unshakeable faith in the Buddha, the Dhamma, and the Saṅgha. The Buddha also addresses a brahmin in verses who believes in purification by bathing in river.

The Buddha distinguishes peaceful 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.

The Buddha explains to Jīvaka the circumstances in which meat may be consumed and the demerit of slaughtering living beings for the Tathāgata or his disciples.

The Buddha instructs Rāhula on how to regard the five aggregates as not-self which he immediately applies to practice. The Buddha then teaches Rāhula on how to meditate on the elements, the divine abodes, unattractiveness, impermanence, and mindfulness of breathing to abandon unwholesome mental qualities and cultivate wholesome mental qualities.

The young brahmin Subha questions the Buddha about whether householders or renunciants are superior and what brings the greatest merit. The Buddha explains that he evaluates actions with discernment, and then teaches the path to companionship with Brahmā through cultivation of the qualities of loving-kindness, compassion, appreciative joy, and equanimity.
