2.883

The Commentary states: Adducing an empowering condition (adhipati-pratyaya) to illustrate the meaning of cause and condition (hetu-pratyaya): just as a lamp's wick and a lamp's flame mutually generate and burn—the flame arises from the wick just as actuality arises from seed; the flame burns the wick just as actuality perfumes seed—hence it is called 'mutual.' This reveals the three dharmas, like bundled reeds supporting one another, functioning as simultaneous causes (sahabhū-hetu). The two dharmas serve as an analogy to illustrate the meaning of cause and condition.
