Padasodhanavāra

Abhidhammapiṭaka · Yamaka (1) · Vol. 38 · Section 98

[98] Is that which is not form (rūpa) not an aggregate (khandha)? Setting aside form, the remaining aggregates are not form, but are aggregates; setting aside form and the aggregates, the rest are neither form nor aggregates. Are those that are not aggregates not the perception aggregate (saññākkhandha)? Yes (āmantā).
