楞伽阿跋多羅寶經註解 2.32

2.32

佛告大慧：「一切法二種緣相，謂外及內。外緣者，謂泥團、柱、輪、繩、水、木、人工，諸方便緣有瓶生。如泥瓶，縷疊、草席、種牙、酪酥等方便緣生亦復如是，是名外緣前後轉生。」

The Buddha told Mahāmati: "All dharmas have two kinds of conditional characteristics: external and internal. As for external conditions, through various expedient conditions such as a lump of clay, a pillar, a wheel, a cord, water, wood, and human craft, a jar arises. Just like a clay jar, arising through expedient conditions such as thread and cloth, straw and a mat, a seed and a sprout, milk and ghee, is also like this. This is called external conditions giving rise [to things] through successive transformation."
