大方廣佛華嚴經隨疏演義鈔 54.19

54.19

疏「不離本處」等者，今經但云「各申右手」，論經云「爾時十方諸佛不離本處，以神通力各申右手」，故疏為此釋。言「即四通」者，《智論》云「一如意通，轉變自身，以大音聲聞一切等。二者幻通，轉變外事。三法智通，智法無礙。四聖自在通，能於苦中生於樂想，於彼樂中能生苦想，於苦樂中生於捨想。如是一切。」今於自身但延促一多，故是如意非餘三也。

Regarding the commentary's "Without departing from their original places, and so forth": the present sūtra merely says, "Each extended their right hand." The sūtra text [cited in] the Śāstra says, "At that time, the Buddhas of the ten directions, without departing from their original places, each extended their right hand by their supernatural power." Thus, the commentary provides this explanation. Regarding "namely, the four supernatural powers": the Dazhidulun says, "First is the power of base transformation (ṛddhi), transforming one's own body, making all hear with a great sound, and so on. Second is the power of illusion, transforming external things. Third is the power of Dharma-cognition, cognition and phenomena being unimpeded. Fourth is the power of noble mastery, capable of generating the idea of pleasure within suffering, capable of generating the idea of suffering within that pleasure, and generating the idea of equanimity within both suffering and pleasure. And so on for all [such things]." Here, with respect to their own bodies, they merely extend or contract, unify or multiply; hence, it is base transformation (ṛddhi) and not the other three.
