When venerable Ānanda inquires about the Buddha’s frequent abiding in emptiness, the Blessed One describes a gradual progression of abidings in ever-stiller perceptions, each seen as empty of what is absent while discerning what still remains, culminating in the unsurpassed abiding in emptiness.

The Buddha finds Anuruddha, Nandiya, and Kimbila living in exemplary harmony—goodwill in body, speech, and mind; shared duties; noble silence; and an all-night Dhamma discussion every fifth day. They can enter the four jhānas and the formless attainments at will, culminating in the exhaustion of the mental defilements from having seen with wisdom.

A series of questions and answers between Venerable Sāriputta and Venerable Mahākoṭṭhika that clarify subtle yet important aspects of the teachings. Topics covered include wisdom, consciousness, felt experience, perception, purified mind-consciousness, right view, existence, first jhāna, the five faculties, vital formations, and the release of the mind.

The Buddha provides a detailed analysis of the six sense bases, differentiating worldly feelings based on attachment from those born of renunciation and insight. He outlines a progressive path of abandoning lower states for higher ones, guiding practitioners through refined meditative states toward complete liberation.

In a chance meeting, the Buddha, unrecognized by the bhikkhu Pukkusāti, teaches him to deconstruct experience into six elements, six fields of contact, eighteen mental explorations, and four foundations. He further reveals that all notions of self—such as “I am this” or “I will be that”—are mere conceptions, inherently afflictive, and the peace of Nibbāna is realized by overcoming all conceptual proliferations.

The Buddha describes the three elements of escape - renunciation, formless element and cessation.

The formless element is more peaceful than the form realm. Yet, cessation is more peaceful than the formless element.

The five higher fetters - 1) Passion for worldly existence, 2) passion for formless existence, 3) conceit, 4) restlessness, and 5) ignorance - are described in brief. The Noble Eightfold Path is the way for direct knowledge, full understanding, complete exhaustion, and giving up of these five higher fetters.
