The Buddha declares he did not claim unsurpassed awakening until he experientially understood the five aggregates in their four phases: their nature, their arising, their cessation, and the way of practice leading to their cessation.

The Buddha explains the distinction between an ordinary person and a wise disciple using the metaphor of two darts. While both experience the first dart of physical pain, the ordinary person adds a second dart of emotional suffering through aversion and ignorance. The wise disciple remains unattached, experiencing only the first feeling without reinforcing suffering.

Seeing the vanishing nature of the experience that arises with each contact—whether felt as pleasant, painful, or as neither-painful-nor-pleasant—one becomes dispassionate towards it.

The Buddha describes the three felt experiences that are experienced on contact through the sense doors - pleasant, painful, and neither-painful-nor-pleasant.

The Buddha explains the four kinds of nutriments that sustain beings that are existing and support those seeking birth, and how they arise from craving.

When a misguided monk clings to the idea of an unchanging consciousness that “wanders through rebirths,” the Buddha corrects him, revealing the truth of dependent co-arising. Consciousness, like fire, arises only through conditions. Tracing the cycle of existence from the four nutriments and conception to the snare of sensory reaction, he shows the way to the complete exhaustion of craving.

The Buddha describes how to see the three felt experiences that are experienced on contact through the sense doors - pleasant, painful, and neither-painful-nor-pleasant.

The Buddha explains how to completely comprehend the gratification, drawback, and escape in the case of sensual pleasures, form, and felt experience.

The Buddha deconstructs speculative views about the past and future, revealing them as forms of clinging. He exposes subtle attachments within even exalted meditative states, showing that all conditioned experiences are unstable. True liberation lies not in constructed peace, but in non-clinging through full understanding of the six sense bases.

Emerging from seclusion, the Buddha describes dwelling in the meditative state he had experienced immediately after Awakening. He explains that all the mental factors—from wrong view to right collectedness, as well as desire, thought, and perception, whether active or subsided—serve as conditions for feeling, even the attainment of the final goal giving rise to feeling.

The venerable Udaya approaches the Buddha with questions about liberation through final knowledge, the fettering of the world, and how to live mindfully for consciousness to cease.

The Buddha presents a series of similes for the five aggregates - physical form is akin to a lump of foam, feelings akin to water bubbles, perception like a mirage, intentional constructs are like a tree without a core, and consciousness is similar to a magic trick.
