觀音玄義記 1.44

1.44

二「佛從」下，約三性明分證。言「佛從」者，欲對觀音明分滿故。佛於三性六即究滿，良由初心能以三觀觀於六法。應知三性即是性中三德三觀，初發心時須於性三起於修三。六位雖殊、三性無別，是則六即皆是無上人法。故下結云二番問答是分釋無上人法也。

Second, from "The Buddha, from..." onward, explains partial realization in terms of the three natures. The words "The Buddha, from..." are spoken to explain partial and complete realization in comparison with Avalokiteśvara. The Buddha's ultimate fulfillment of the three natures and six identities is truly due to being able at the initial stage of mind to contemplate the six phenomena with the three contemplations. One should know that the three natures are precisely the three virtues and three contemplations within nature; at the initial generation of mind, one must give rise to the three of cultivation from the three of nature. Although the six stages differ, the three natures are not different; thus the six identities are all unsurpassed persons and phenomena. Therefore, the conclusion below states that the two rounds of questions and answers are partial explanations of the unsurpassed person and phenomena.
