Padasodhanavāra

Abhidhammapiṭaka · Yamaka (1) · Vol. 38 · Section 91

[91] Are volitional formations (saṅkhārā) an aggregate (khandha)? Yes. Are aggregates the aggregate of perception (saññākkhandha)? The aggregate of perception is both an aggregate and the aggregate of perception; the remaining aggregates are aggregates, not the aggregate of perception.
