It will be good to have understanding of what are The Five Aggregates (Pancakkhandha).
The khandha are collections of past, future, or present, internal or external, gross or subtle, disliked or liked, far or near (atītānāgatapaccuppannaṃ vā ajjhattaṃ vā bahiddhā vā oḷārikaṃ vā sukhumaṃ vā hīnaṃ vā paṇītaṃ vā yaṃ dūre santike).
