The Buddha describes the three mental faculties - the faculty that senses ‘I will know the unknown,’ the faculty of awakening, and the faculty of one who is awakened.

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. The Blessed One 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 the difference between cultivation and lack of cultivation with regard to body and mind, and recounts his own journey to full awakening.

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 teaches in detail how to develop mindfulness while breathing in and out through sixteen naturally unfolding steps, showing how their cultivation fulfills the four establishments of mindfulness, which in turn fulfill the seven factors of awakening, culminating in true knowledge and liberation.
