The 6 Classes of Perception

Overview

Perception (Saññā) is the mental factor that recognizes, labels, and makes sense of the raw data provided by contact. It is what allows us to identify a red shape as an “apple.” Like the other aggregates, it is structurally divided into six classes based on the sense object being perceived.

The List

1. Rūpasaññā - Perception of forms: Recognizing and labeling visual objects.
2. Saddasaññā - Perception of sounds: Recognizing and labeling auditory objects.
3. Gandhasaññā - Perception of odors: Recognizing and labeling smells.
4. Rasasaññā - Perception of tastes: Recognizing and labeling flavors.
5. Phoṭṭhabbasaññā - Perception of tangibles: Recognizing and labeling physical sensations.
6. Dhammasaññā - Perception of mental objects: Recognizing and labeling ideas, concepts, and mental states.
