6.155

不離法界者。佛是極證之人，已全是法界，眾生雖未能證緣生無體，亦同法界，豈將法界度於法界？是故偈云：「平等等也。」

"Not apart from the dharmadhātu": the Buddha is one who has fully realized [it] to the utmost and is already entirely the dharmadhātu; although sentient beings have not yet realized that dependent origination lacks substantial entity, they are likewise identical with the dharmadhātu. How could one use the dharmadhātu to deliver the dharmadhātu? Therefore the verse says: "Equality and so forth."
