無量壽經連義述文贊 2.7

2.7

經曰「譬如幻師」至「在意所為」者，述云：此第二、歎化善巧。有二：此初、喻也。菩薩顯化巧順物宜，可云幻師。所起化相如顯眾像，起化之德如本學明。化法即以習學為本，故云本。學之委善，故云學明了。學成起化，任意所為，故云在意所為。遠法師云「學成起用成在於心」，故云在意。任意化，故云所為。此恐非也。學未成亦在心，故今不存也。

The sūtra says: from "just like an illusionist" up to "performing as willed in the mind." The commentary states: This second part praises the skillfulness of transformation. There are two: this initial part is the simile. Bodhisattvas manifesting transformations skillfully conform to what is suitable for beings, so they can be called 'illusionists'. The transformed appearances they manifest are like displaying various images; the virtues that produce the transformations are like the thorough mastery of their original training. The methods of transformation take practice and training as their foundation, hence called 'original'. Studying them comprehensively and skillfully, it is called 'thorough mastery in training'. Once the training is accomplished and transformations arise, they act as they will, hence called 'performing as willed in the mind'. Master Yuan said: "When training is accomplished and function arises, the accomplishment lies in the mind," hence called 'in the mind'; and "transforming at will," hence called 'performing'. This is probably incorrect: before training is accomplished it is also in the mind, hence I do not retain it here.
