[2099] An internal phenomenon (ajjhatta-dhamma) is a condition for an internal phenomenon by kamma condition (kamma-paccaya): conascent (sahajāta), asynchronous (nānākkhaṇika).
Conascent: internal volition (cetanā) is a condition for the associated aggregates and for mind-originated forms (cittasamuṭṭhāna-rūpa) by kamma condition.
Asynchronous: internal volition is a condition for the resultant internal aggregates and for forms due to kamma performed (kaṭattā-rūpa) by kamma condition.
