金光明經玄義 1.21

1.21

若見此十法門，若同若異亦是一法門，作一切法門相。若同若異相相明了，即百法千法萬法，恒沙塵數亦如是。《華嚴》云「一法門無量法門而為眷屬」，《首楞嚴》和香丸，《大品》裹珠，《法華》一地所生，《涅槃》大海水浴，皆是其義。

If one sees these ten dharma gates, whether identical or distinct, they are also a single dharma gate, forming the marks of all dharma gates. If their identical and distinct marks are clearly evident, then a hundred dharmas, a thousand dharmas, ten thousand dharmas, and those as numerous as sands of the Ganges and particles of dust are also like this. The Avataṃsaka says, "One dharma gate has immeasurable dharma gates as its retinue"; the blending of the incense pill in the Śūraṅgama, the wrapped jewel in the Pañcaviṃśatisāhasrikā, the sprouting from the single ground in the Lotus Sūtra, and bathing in the great ocean in the Mahāparinirvāṇa Sūtra are all of this meaning.
