問：佛入空觀，猶見如外有佛、佛外有如不？答：若如佛為二，猶為二觀，何名不二？既不見二，亦不見一，如是不見五句，而如佛宛然。斯處幽微，唯佛境界。問：既不見五句，何名不二？答：良以見五，明為二見。以不見五，故稱不二。問：如佛不異，可名不二。而境智宛然，何名不二？答：二常不二，故名不二。

Question: When the Buddha enters the contemplation of emptiness, does he still see a Buddha outside suchness, or suchness outside the Buddha? Answer: If suchness and Buddha were two, that would still be a contemplation of duality; how could it be called nonduality? Since he sees neither two nor one, thus not seeing the five propositions, yet suchness and Buddha are distinctly present. This realm is subtle and profound, the domain of the Buddha alone. Question: Since he does not see the five propositions, why is it called nonduality? Answer: It is precisely because seeing five clearly constitutes a view of duality; because he does not see five, it is called nonduality. Question: That suchness and the Buddha are not different may be called nonduality; but when object and cognition are distinctly present, how is it called nonduality? Answer: Duality is constantly nondual; hence it is called nonduality.
