大方廣佛華嚴經隨疏演義鈔 33.17

33.17

疏「念處有二」下，釋第二此中誰是我句。謂有問言：準念處觀，觀身不淨、觀受是苦、觀心無常、觀法無我，今何觀身為無我耶？故今答云：有通有別。上以別難，今約通說，故於觀身得作無我及苦無常不淨之觀，今但舉無我耳。

Regarding the commentary's "The applications of mindfulness are of two kinds" and so forth: this explains the second line, "Who is the self in this?" That is to say, there is a question asking: according to the contemplation of the applications of mindfulness, one contemplates the body as impure, contemplates feeling as suffering, contemplates the mind as impermanent, and contemplates dharmas as non-self; why now contemplate the body as non-self? Therefore it now answers, saying: there are general and specific [modes]. The objection above was made according to the specific; now it speaks in terms of the general. Therefore, in contemplating the body, one can cultivate the contemplations of non-self, suffering, impermanence, and impurity; here it merely mentions non-self.
