Question: Regarding the illusions of karma conforming to defilement, in terms of the good according with the true, they can be accomplished; if in terms of the non-good and good opposing the true, how can they act as illusory non-good? Answer: If non-good opposes the true, it is granted that it is also not entirely an illusory non-good; in terms of giving rise to aversion and renunciation, and in terms of generating understanding through it, it can also be an illusory non-good. Alternatively, defiled illusions are ignorance, which has neither essence nor true function; in terms of the distinctions of that ignorance, one knows names and meanings and can explain the principle, and because they explain the true, they can be illusory defilement. Furthermore, in terms of that ignorance, the illusory essence is originally non-existent, and because it is non-existent, it lacks true function; in terms of knowing names and meanings, this illusory essence is not separate from the true.
