Sanna

Meaning

The third of the five aggregates: the capacity to distinguish and recognise the marks of experience. In SN 22.79 the Buddha explains it with a simple example - saññā recognises “blue, yellow, red, white.”

The ear catches a sound and saññā distinguishes it as a clap. The eye catches a patch and it is “a face, familiar.” All this happens before any active thinking or interpretation. Saññā sorts current experience into familiar categories, allowing us to recognise what we see, hear, feel and imagine.

A dangerous mechanism

Ordinary life is impossible without this mechanism: saññā lets us recognise letters, faces, the way home and the handle on a cup. Trouble begins not with recognition itself but at the moment the recognised category is imperceptibly identified with “true” reality.

“The boss” - and with the recognition yesterday’s grievance rises. “Monday” - and the habitual gloom arrives, although today’s Monday has not yet done anything to us.

MN 18 describes the chain: what one feels, one perceives; what one perceives, one thinks about; what one thinks about can proliferate into papañca, an endless world of mental elaboration. A small pebble of recognition acquires an avalanche of personal stories.

Four systemic failures

In AN 4.49 the Buddha describes four classical vipallāsa - distortions operating at the level of perception (saññā), mind (citta) and view (diṭṭhi). We are inclined to take:

• the impermanent for the permanent
• the painful and unsatisfactory for the pleasant
• what is not self for “I” and “mine”
• the unattractive for the attractive

The error can begin at the level of how something is perceived and then be consolidated by emotions, thoughts and convictions. Such a process cannot be defeated by logical argument - one has to learn to see the very way experience assembles into a familiar picture.

Perception can be trained

The good news: saññā can be deliberately cultivated. In MN 121 the practice of emptiness is built as a successive replacement of perceptions:

• the practitioner stops attending to “village” and “people” and sustains the perception of forest
• then leaves forest for the perception of earth
• then moves on to boundless space and ever subtler states

In AN 10.60 the Buddha lists outright the perceptions to be developed: the perception of impermanence (anicca-saññā), of not-self, of unattractiveness, of danger, of abandoning, of dispassion, of cessation and others.

Buddhist practice does not try to get rid of labels altogether. It teaches one to see more precisely and to choose modes of perception that lead to liberation rather than to clinging.

In practice

A game for the day: notice the shift from plain recognition to the story the mind manages to build around it.

• a sound: “knock” → “the neighbour is drilling again” → “how much longer!”
• a sensation in the belly: “tightening” → “anxiety” → “everything is lost”

We do not have to automatically go with the first thought, reaction or papañca that follows recognition. This is exactly where freedom begins.
