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.

When a debate arises regarding the classification of feelings, the Buddha explains that different presentations can be valid in their context. True understanding, he explains, fosters concord rather than quarrel. He then charts a progressive hierarchy of happiness starting with worldly pleasures.

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 venerable Sāriputta delivers a comprehensive exposition on “Right View,” detailing sixteen ways a noble disciple achieves clarity in the Dhamma. By understanding the wholesome and unwholesome, nutriments, the Four Noble Truths, dependent origination, and the taints—including their arising and cessation—a disciple abandons underlying tendencies and realizes the end of suffering.

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 describes how dependent on the diversity of elements, there arises a diversity of perceptions, intentions, contacts, felt experiences connected with contact, desires, fevers, quests, and acquisitions.

The six sense elements condition a causal chain sequentially leading to diverse perceptions, intentions, contacts, felt experiences, desires, fevers, quests, and acquisitions. The Buddha emphasizes this dependent arising is strictly one-way: subsequent states do not condition the preceding elements.

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

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 employs five powerful metaphors to expose the coreless nature of the aggregates. He likens form to foam, feeling to a water bubble, perception to a mirage, intentional constructs to a hollow banana tree, and consciousness to a magician’s illusion.

Which things should a virtuous bhikkhu radically attend to? Venerable Sāriputta explains how a bhikkhu at each stage of awakening should radically attend to the five aggregates that are subject to clinging.

A teaching on the fearless resolve that severs the lower fetters, followed by the exact inquiry for the wearing away of the taints.

By mapping how suffering dynamically depends on internal conditions—including felt experience, craving, clinging, and perturbation—the Buddha demonstrates that liberating knowledge arises from seeing pairs of principles exactly as they are.
