首楞嚴義疏注經 9.371

9.371

「爾時天魔候得其便，飛精附人，口說經法，其人殊不覺知魔著，亦言自得無上涅槃，來彼求知善男子處，敷座說法。是人無端於說法處得大寶珠，其魔或時化為畜生，口銜其珠及雜珍寶、簡策、符牘諸奇異物，先授彼人，後著其體，或誘聽人，藏於地下，有明月珠照曜其處，是諸聽者得未曾有。多食藥草，不餐嘉饌，故或時日餐一麻、一麥，其形肥充，魔力持故。誹謗比丘，罵詈徒眾，不避譏嫌。」

"At that time, the heavenly demon, waiting to seize the opportunity, flies its essence to possess a person, who preaches the sūtras and Dharma with his mouth. That person does not realize at all that a demon has possessed him, and also claims that he has personally attained unsurpassable nirvāṇa. He comes to the place of that good man who is seeking knowledge, arranges a seat, and preaches the Dharma. For no reason, this person obtains a great precious pearl at the place of preaching the Dharma; or sometimes the demon transforms into an animal holding in its mouth that pearl, various rare treasures, bamboo slips, tallies, registers, and various strange objects, first giving them to that person and later possessing his body; or he entices listeners and hides underground, where a bright-moon pearl illuminates the place, causing all the listeners to obtain what they had never had before. He eats mostly medicinal herbs and does not consume fine foods, or sometimes eats just one sesame seed and one grain of wheat a day, yet his form is plump and full because the demonic power sustains him. He slanders bhikṣus, reviles disciples, and does not shun ridicule or suspicion."
