仁王般若經疏 2.91

2.91

佛告大王：「汝先言云何眾生相可化？若以幻化身見幻化者，是菩薩真行化眾生。眾生識初一念識異木石，生得善、生得惡，惡為無量惡識本，善為無量善識本。」

The Buddha told the great king: "You said before, 'How can the marks of sentient beings be transformed?' If with an illusory body one sees what is illusory, this is the bodhisattva's true practice of transforming sentient beings. The sentient being's consciousness at the first single thought-moment of consciousness is different from wood and stone: it has naturally born good and naturally born evil; evil is the root of immeasurable evil consciousnesses, and good is the root of immeasurable good consciousnesses."
