Saṃyutta Nikāya · Discourse 35.1

The Interior as Impermanent

Ajjhattāniccasutta — Aniccavagga

Setting
Sāvatthī, Jeta's Grove, Anāthapiṇḍika's monastery
Speakers
The Buddha addressing the mendicants
Form
A direct declaration applied to all six interior sense fields in turn, closing with the standard disillusionment-to-liberation formula
Length
~2 minutes to read
Northern parallel
A rough counterpart may exist in the Chinese Saṃyukta-āgama (T99), though this reading guide does not assert a specific matching sutra number
Difficulty
★★☆☆☆ — the three-step logical chain (impermanent, therefore suffering, therefore not-self) rewards careful reading

Why this discourse

This discourse opens Saḷāyatanasaṃyutta ("Linked Discourses on the Six Sense Fields") and, with it, Book IV (Saḷāyatanavagga) — the largest saṃyutta this project has yet encountered, 248 discourses across 19 vaggas. Where Book III's own Khandhasaṃyutta (SN 22) opened by declaring the five aggregates impermanent, this discourse opens with the six interior sense fields (eye, ear, nose, tongue, body, mind) instead, tracing the identical three-step chain: what's impermanent is suffering, what's suffering is not-self, and what's not-self should be seen for what it truly is. This single discourse establishes the logical chain and the closing liberation formula that Aniccavagga's own remaining eleven discourses will systematically vary.

Reading guide

Six interior sense fields, one shared declaration

"The eye is impermanent … the ear … the nose … the tongue … the body … the mind is impermanent" — the same three-step chain (impermanent, therefore suffering, therefore not-self) applied identically across all six of the interior sense fields, the faculties themselves rather than what they perceive.

A logical chain, not six separate claims

The discourse doesn't merely assert impermanence six times; it explicitly derives suffering from impermanence and not-self from suffering, giving each of the six sense fields the identical three-link chain rather than treating them as six unrelated observations.

The standard formula for right seeing

"This is not mine, I am not this, this is not my self" — the same threefold negation this project has already traced applied to the five aggregates in Book III, now applied to the six sense fields instead.

From disillusionment to full liberation, in four short steps

The discourse closes with this project's own familiar liberation sequence: disillusionment, fading desire, freedom, and the knowledge of that freedom, ending in the standard declaration that rebirth is ended and the spiritual journey complete — establishing the closing formula every one of this vagga's later, more compressed discourses will assume.

The text

The complete discourse: the opening greeting, the six-fold impermanence declaration, and the full closing liberation formula. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

§1So I have heard. At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery. There the Buddha addressed the mendicants, “Mendicants!” “Venerable sir,” they replied. The Buddha said this:

§2“Mendicants, the eye is impermanent. What’s impermanent is suffering. What’s suffering is not-self. And what’s not-self should be truly seen with right understanding like this: ‘This is not mine, I am not this, this is not my self.’ The ear is impermanent. …

§3The nose is impermanent. …

§4The tongue is impermanent. …

§5The body is impermanent. …

§6The mind is impermanent. What’s impermanent is suffering. What’s suffering is not-self. And what’s not-self should be truly seen with right understanding like this: ‘This is not mine, I am not this, this is not my self.’ Seeing this, a learned noble disciple grows disillusioned with the eye, ear, nose, tongue, body, and mind. Being disillusioned, desire fades away. When desire fades away they’re freed. When they’re freed, they know they’re freed. They understand: ‘Rebirth is ended, the spiritual journey has been completed, what had to be done has been done, there is nothing further for this place.’”
