The Buddha expounds the noble right collectedness complete with its supporting conditions, clarifying how the factors of the noble eightfold path give rise to either mundane or supramundane fruits. He shows how right view leads to the sequential development of the path, culminating in right knowledge and right liberation.

The Buddha teaches about the person who has had “a single auspicious night”. One who neither revives the past nor places hope in the future, but diligently discerns present phenomena with insight—without taking them as self, and practices with urgency today without being carried away by presently arisen phenomena, that wise one is one who has had a single auspicious night.

When venerable Sāriputta meets venerable Puṇṇa Mantāṇiputta, he asks whether the spiritual life is lived for the sake of various purifications—of conduct, mind, view, overcoming doubt, knowing the path, knowing the practice, and knowledge and vision. Venerable Mantāṇiputta explains, with the simile of seven relay chariots, that each stage of purification serves only as a step toward the next, culminating in final Nibbāna without clinging—the true goal of the spiritual life.

In the Gosiṅga Sal wood park, Sāriputta asks several elder disciples what kind of monk illuminates the place. Each answers based on their personal strength — learning, seclusion, divine eye, asceticism, Dhamma dialogue and mastery over mind. They present their answers to the Buddha, who affirms that all have spoken well and then shares his own answer.

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 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.

The Buddha advises to 1) dwell contemplating the unattractive nature of the body, 2) establish mindfulness as the first priority while breathing in and out, and 3) observe impermanence in all conditioned phenomena.

When one knows and sees the four noble truths, there is the wearing away of the taints.

Only after fully understanding the gratification, drawback, and escape in the case of form, felt experience, perception, intentional constructs, and consciousness, the Buddha declared that he had attained the unsurpassed perfect awakening.

Before his awakening, the Bodhisatta reflected on the gratification in the world, the drawback in the world, and the escape from it.

The Buddha describes his quest for gratification in the world, drawback in the world, and the escape from it. He subsequently experientially realized gratification, drawback, and escape as they truly are, leading to his unshakable liberation.

The Buddha explains the proximate causes of non-regret, joy, tranquility, and other qualities leading to liberation, contrasting how they are fulfilled in a virtuous person versus an unprincipled person.
