首楞嚴義疏注經 9.380

9.380

神境之通離欲方得，貪心強取即陷魔羅。必若真通，刀豈能沮。以斯取驗，邪正可分。身著白衣受比丘禮者，准《仁王經》「白衣高座、比丘地立，佛法滅相。」菩薩戒中亦同此說。

The supernormal power of psychic realms is obtained only by abandoning desire; if one forcibly takes it with a covetous mind, one promptly falls into Māra. If it were truly supernormal power, how could blades obstruct it? Taking this as verification, the deviant and the correct can be distinguished. As for "wearing white robes, receives the prostrations of bhikṣus," according to the Humane Kings Sūtra: 'White robes on the high seat, bhikṣus standing on the ground, is the mark of the extinction of the Buddha's Dharma.' The Bodhisattva Precepts also state the same thing.
