When we say “I”, what exactly do we mean? The Buddha answered this question by analysing a person into five groups or “heaps” called the five aggregates (pañcakkhandha). They are not parts of a soul, but changing processes. Seeing them clearly is one of the most direct ways to understand not-self, and they appear again and again throughout the canon, especially in the Khandha Saṃyutta (SN 22).
The five aggregates
- Form (rūpa) — the physical body and the material world, made of the four great elements: earth (solidity), water (cohesion), fire (heat) and air (motion).
- Feeling (vedanā) — the pleasant, unpleasant or neutral tone of every experience. Not emotion, but the basic “flavour” of an experience.
- Perception (saññā) — recognising and labelling: “this is blue”, “this is my friend”.
- Mental formations (saṅkhārā) — intentions, emotions, habits and reactions such as desire, kindness or anger. This is where kamma is made.
- Consciousness (viññāṇa) — awareness through the six senses.
Imagine hearing a song on the radio. There is the sound and the ear (form), awareness of the sound (consciousness), recognition that it is your favourite song (perception), a pleasant feeling, and then reactions — the wish to turn it up, a memory, a smile (mental formations). All five work together in a single moment, and all five change from moment to moment.
The Discourse on the Characteristic of Not-Self
The Buddha’s second discourse, the Anattalakkhaṇa Sutta (SN 22.59), was given to his first five disciples at the Deer Park near Bārāṇasī. He points out that if form were truly self, it would not lead to affliction, and we could say, “Let my body be like this; let it not be like that.” But we cannot. The same is true of feeling, perception, formations and consciousness.
He then asks the five monks to see every kind of form, feeling and so on — past, future or present, internal or external, gross or subtle, inferior or superior, far or near — with right wisdom as “this is not mine, this I am not, this is not my self”. Seeing this way, they became disenchanted, dispassionate and free. According to the sutta, all five were fully liberated as they listened.
Five beautiful similes
In another discourse (SN 22.95) the Buddha compares the aggregates to things that look solid but have no core:
- Form is like a lump of foam on a river.
- Feeling is like a bubble on water in the rain.
- Perception is like a mirage.
- Mental formations are like the trunk of a plantain tree, which has no heartwood.
- Consciousness is like a magician’s illusion.
The similes do not say that experience is unreal. They say that when we look closely, we find no permanent essence inside it.
The aggregates of clinging
The Buddha often speaks of the “five aggregates of clinging” (upādānakkhandha). In the first of the Four Noble Truths he sums up suffering in a single phrase: in short, the five aggregates of clinging are suffering. Suffering does not come from having a body or feelings, but from clinging to them as “mine”, “I” and “my self”.
In SN 22.22 he calls the five aggregates a heavy burden: craving picks the burden up, and Nibbāna is laying it down. And when the elderly householder Nakulapitā came to him in poor health, the Buddha advised him to train like this: “Though my body is sick, my mind will not be sick” (SN 22.1). When the body falls ill, we can suffer twice: once from the pain, and again from the sense that “I” am being harmed. The Buddha elsewhere calls this the second arrow (SN 36.6). Wisdom removes the second arrow.
Common misunderstandings
- “So I do not exist.” The nun Vajirā answered this with a simile (SN 5.10): just as the word “chariot” is used when its parts are assembled, so we speak of “a being” when the aggregates are present. A person exists conventionally, as a process — just not as an unchanging self.
- “The body is bad, so I should neglect it.” The point is to stop clinging, not to stop caring. The Buddha cared for his body and taught moderation.
- “The self is hiding somewhere else.” In MN 44 the nun Dhammadinnā lists twenty ways of taking the aggregates as self — for example, seeing the self as owning the body, or as inside feeling. All of them are to be seen through.
In practice
- In meditation, notice which aggregate is most obvious right now — a sensation, a feeling, a label, a reaction or plain awareness.
- When a strong emotion arises, recognise it as a mental formation that has arisen and will pass.
- When you feel pain, notice the first arrow, and see whether you can decline the second.
- Reflect: “This is not mine, this I am not, this is not my self” — gently, without forcing.
Key point: the aggregates are the “what” of experience; dependent origination is the “how”. Together they explain a person without an unchanging self. Question to reflect on: which of the five do you most strongly take to be “me”?
