Five Aggregates

It is through the five aggregates that the world is experienced, and nothing is experienced apart from the five aggregates.

The five aggregates are :

1) "Form" or "Matter"
External and internal matter. Externally, "Form" is the physical world. Internally, "Form" includes the material body and the physical sense organs.

2) "Sensation" or "Feeling"
Sensing an object as either pleasant or unpleasant or neutral.

3) Perception", "Conception" or "Cognition"
Register whether an object is recognized or not ( for instance, the sound of a whistle or the shape of a flower ).

4)  "Mental Formations"
All types of mental habits, thoughts, ideas, opinions, prejudices, compulsions, and decisions triggered by an object.

5) "Consciousness" or "Discernment"
The base that supports and discerns all experiences.
