2.817

覺前能悟，悟是所覺。悟既成所，覺又名能，展轉無窮，皆成能所。能所及處皆是相待，了此無定，故離前；非計所不及，謂免諸過。不覺此計，又是眾生。眾生者，不定執一之謂也。

Being aware of the former subject that can awaken, that awakening becomes an object of awareness. Once awakening has become an object, awareness is again called the subject; turning over endlessly, all become subject and object. Wherever subject and object reach, all are mutually dependent; understanding that these are indeterminate, one is free from the previous [marks]. Calculating that it is not reached, one thinks one has escaped all faults. Not realizing that this calculation is itself [the mark of] a sentient being. 'Sentient being' means not determinately grasping onto any single one.
