仁王般若經疏 2.91

2.91

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."
