首楞嚴義疏注經 9.348

9.348

心欲求元，魔精附物，說肉身為三德之本，指相生為常住之因，清淨之方只此穢境，相好之體全是我身。妄本既宣，邪信便發，魔力所制，更不推移，盡命歸心，從邪敗正。

When the mind desires to seek the source, the demon essence possesses an entity, claiming the physical body to be the root of the three virtues and pointing to reproduction as the cause of permanent abiding: the pure realm is merely this defiled environment, and the body of marks and signs is entirely my own body. Once the root of delusion is proclaimed, deviant faith then arises; controlled by the demonic power, it shifts no more, as they commit their lives and dedicate their minds, following deviation and ruining correctness.
