問：不二當體是門，以何為證？答：其例甚多。如法界法門，不可從非法界入於法界，亦不可從法界更入非法界非不法界，故法界當體為門。問：法界何故不得更入非法界非不法界？答：經云「廣大如法界」，歎法界圓滿究竟，故不得更有所入。問：法界與不二何異耶？答：同是一道，但名字不同。何以知之？經云「無盡平等妙法界，皆悉充滿如來身」。法界平等，即是不二。不二廣大無法不含，即是法界也。

Question: What serves as proof that nonduality is itself the gate? Answer: Such examples are very numerous. As with the Dharma gate of the dharmadhātu: one cannot enter the dharmadhātu from non-dharmadhātu, nor can one further enter neither dharmadhātu nor non-dharmadhātu from the dharmadhātu; hence the dharmadhātu is itself the gate. Question: Why can one not further enter neither dharmadhātu nor non-dharmadhātu from the dharmadhātu? Answer: The sūtra states, "vast as the dharmadhātu," praising the dharmadhātu as consummate and ultimate; hence there is nothing further to enter. Question: How does the dharmadhātu differ from nonduality? Answer: They are the same single path, differing only in name. How is this known? The sūtra states: "The inexhaustible, equal, and wondrous dharmadhātu completely fills the Tathāgata's body." The equality of the dharmadhātu is precisely nonduality. Nonduality is vast and contains no dharma that is not included; that is precisely the dharmadhātu.
