大方廣佛華嚴經隨疏演義鈔 23.35

23.35

On the commentary’s "Looking from the person to the practice" and below: third, discriminating ambiguities, because the sūtra states that "the Tathāgata's spheres of practice may be confused with the cognitive realm, since they are what compassion and wisdom practice." Within this, first it directly discriminates, and then cites evidence. That is to say, because the Buddha is the agent of practice, the practice of compassion and wisdom is what is practiced. It is not like in the case of the cognitive realm where compassion and wisdom are the agents of practice and tathatā and sentient beings are what is practiced. Therefore it says, "Looking from the person to the practice, it designates them as 'what is practiced'."
