[1146] A phenomenon (dhamma) leading to accumulation (ācayagāmī) is a condition, by presence condition (atthi-paccaya), for a phenomenon neither leading to accumulation nor leading to dispersal (nevācayagāmi-nāpacayagāmī): conascent, postnascent.
Conascent (sahajāta): aggregates (khandhā) leading to accumulation are a condition, by presence condition, for mind-originated forms (cittasamuṭṭhāna-rūpa).
Postnascent (pacchājāta): aggregates leading to accumulation are a condition, by presence condition, for this prenascent (purejāta) body.
