The five aggregates consist of the body (form) and four functions of the mind: feelings and sensations, perception, mental formations and consciousness. The body houses the five sense organs and the thinking faculty as the sixth sense organ. As the six sense organs get in touch with phenomena from the external and internal world, the mind’s aggregates respond with the arising of feelings and sensations, perception, mental formations and consciousness.
Aggregate is a Buddhist concept as the Buddha gave new meaning to the Pāli word khandha which simply means a pile, bundle, heap, tree or tree trunk.
Refer to the text “The Five Aggregates and the Sutta on the No-Self” for more details.
