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 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.
Shortly after the Buddha's final Nibbāna, Venerable Ānanda addresses the brahmins Gopaka Moggallāna and chief minister Vassakāra, clarifying that the Buddha appointed no successor, establishing the Dhamma itself as the refuge for the Saṅgha. He outlines ten qualities that make a bhikkhu worthy of veneration and distinguishes the meditations praised by the Buddha from those based on hindrances.
In Linked Discourses (Saṃyutta Nikāya)
The five hindrances - 1) sensual desire, 2) ill will, 3) dullness and drowsiness, 4) restlessness and worry, and 5) doubt - are described in brief. The Noble Eightfold Path is the way for direct knowledge, full understanding, complete exhaustion, and giving up of these five hindrances.
The five hindrances - 1) sensual desire, 2) ill will, 3) dullness and drowsiness, 4) restlessness and worry, and 5) doubt - are described in brief. The four establishments of mindfulness should be cultivated for directly knowing, full understanding, complete exhaustion, and giving up of these five cords of sensual pleasure.
In Numerical Discourses (Aṅguttara Nikāya)
The Buddha explains what causes the hindrances to arise and how to abandon them.
In Inspired Utterances (Udāna)
The Buddha expresses an inspired utterance about the qualities of a person who falls under the sway of Māra and of one who overcomes all bad destinations.
