修習止觀坐禪法要 1.149

復次，若見魔境不謝，不須生憂；若見滅謝，亦勿生喜。所以者何？未曾見有人坐禪見魔化作虎狼來食人，亦未曾見魔化作男女來為夫婦。當其幻化，愚人不了，心生驚怖及起貪著，因是心亂，失定發狂，自致其患，皆是行人無智受患，非魔所為。若諸魔境惱亂行人，或經年月不去，但當端心正念堅固，不惜身命，莫懷憂懼，當誦大乘方等諸經治魔呪，默念誦之。存念三寶。若出禪定，亦當誦呪自防，懺悔慚愧，及誦波羅提木叉。邪不干正，久久自滅。魔事眾多，說不可盡，善須識之。

Furthermore, if one sees demonic states not vanishing, there is no need to give rise to sorrow; if one sees them vanish, neither should one give rise to joy. Why is this? One has never seen a seated meditator seeing a demon transform into a tiger or wolf and come to eat them, nor has one ever seen a demon transform into a man or woman to become husband or wife. When such illusory transformations appear, foolish people fail to understand, and their minds give rise to panic and produce greedy attachment. Disquieted by this, they lose concentration and go mad, bringing this misfortune upon themselves; it is all due to the practitioner's lack of wisdom that they suffer misfortune, not the doing of Māra. If various demonic states afflict and agitate the practitioner, and perhaps do not depart over months or years, one must simply rectify the mind with firm correct mindfulness, spare neither body nor life, harbour neither sorrow nor fear, and recite the demon-quelling dhāraṇīs from the Mahāyāna Vaipulya sūtras, reciting them silently. Keep the Three Jewels in mind. If one emerges from dhyāna-concentration, one should also recite spells to protect oneself, repent with shame and conscience, and recite the Prātimokṣa. The deviant cannot infringe upon the correct; over time they will naturally vanish. Demonic affairs are numerous and cannot be fully spoken of; one must recognize them well.
