The skandhas are the five "heaps" or aggregates, the components of an intelligent being: form, feelings, perceptions, impulses and emotions, and acts of consciousness. Buddhism holds that there is no individuality or self which transcends these five heaps. The dhatu are the eighteen realms of sense, i.e., the six sense organs (eyes, ears, nose, tongue, body, and mind), their objects or conditions, and their perceptions.
