[2186] In dependence on an invisible impinging phenomenon (anidassana-sappaṭigha dhamma), an invisible impinging phenomenon arises by mutuality condition (aññamañña-paccaya): in dependence on one invisible impinging primary element (mahābhūta), two primary elements arise; in dependence on two primary elements, one primary element arises.
In dependence on an invisible impinging phenomenon, an invisible non-impinging phenomenon (anidassana-appaṭigha) arises by mutuality condition: in dependence on the invisible impinging primary elements, the water element (āpo-dhātu) arises.
In dependence on an invisible impinging phenomenon, invisible impinging and invisible non-impinging phenomena arise by mutuality condition: in dependence on one invisible impinging primary element, two primary elements and the water element arise; in dependence on two primary elements, one primary element and the water element arise.
