[43] Is form (rūpa) the form aggregate (rūpakkhandha)?
What is of a pleasing nature (piyarūpa) and of an agreeable nature (sātarūpa) is form, but not the form aggregate; the form aggregate is both form and the form aggregate.
Are aggregates (khandhā) the perception aggregate (saññākkhandha)?
The perception aggregate is both an aggregate and the perception aggregate; the remaining aggregates are aggregates, but not the perception aggregate.
