法華論疏 3.359

3.359

釋中云示現彼此所作諸業無差別故，釋意明示現十方分身佛故目之為彼，釋迦之身稱之為此。亦得十方分身相望自為彼此。十方諸佛同欲弘道利人，故云十方諸佛所作諸業無有差別也。又十方分身佛同住淨土、同說一乘、同化菩薩，即是顯諸佛道同，故名所作業無差別。諸佛道既同故，當知今日釋迦亦同諸佛。

In the explanation, it says "because it manifests that the various activities performed by one another are without distinction": the intended meaning of the explanation clarifies that because the emanation-body Buddhas of the ten directions are manifested, they are referred to as "that", while the body of Śākyamuni is called "this". It also can be taken as the emanation bodies of the ten directions viewing each other as "that" and "this". The Buddhas of the ten directions identically wish to propagate the path and benefit people; hence it says that the various activities performed by the Buddhas of the ten directions are without distinction. Furthermore, the emanation-body Buddhas of the ten directions identically dwell in pure lands, identically expound the One Vehicle, and identically transform bodhisattvas; this reveals that the path of all Buddhas is identical, and is therefore named "the activities performed are without distinction". Since the path of all Buddhas is identical, one should know that Śākyamuni today is also identical to all Buddhas.
