觀音玄義 2.30

2.30

五入法門普者，二乘若入一法門，不能入二，何況眾多？若修歷別之行，階差淺深，我唯知此一法門，餘不能知者，此亦非普。若入王三昧，一切悉入其中，譬如王來必有營從，營從復有營從，王三昧亦如是，入此三昧，一切三昧悉入其中，所謂三諦三昧，三諦三昧復有無量法門而為眷屬亦皆悉入王三昧中，故名入法門普。

Fifth, universal entry into dharma-gates: if the two vehicles enter one dharma-gate, they cannot enter a second, let alone many. If one cultivates successive practices with stages of shallow and deep, thinking, 'I only know this one dharma-gate and cannot know the rest,' this too is not universal. If one enters the king of samādhis, all [samādhis] enter into it. For instance, when a king arrives, he must have an entourage, and the entourage also has an entourage; the king of samādhis is also like this. When entering this samādhi, all samādhis enter into it—namely, the samādhi of the three truths. The samādhi of the three truths further has immeasurable dharma-gates as its retinue, all of which also enter into the king of samādhis; therefore, it is called universal entry into dharma-gates.
