首楞嚴義疏注經 9.391

9.391

「又善男子受陰虛妙，不遭邪慮，圓定發明，三摩地中心愛長壽，辛苦研幾，貪求永歲，棄分段生，頓希變易，細想常住。爾時天魔候得其便，飛精附人，口說經法，其人竟不覺知魔著，亦言自得無上涅槃，來彼求生善男子處，敷座說法。好言他方往還無滯，或經萬里瞬息再來，皆於彼方取得其物，或於一處在一宅中數步之間，令其從東詣至西壁，是人急行，累年不到，因此心信，疑佛現前。」

"Furthermore, as the good person finds the aggregate of feeling empty and subtle, unassailed by deviant thoughts, and perfect concentration shines forth, within his samādhi his mind craves long life; toilsomely examining subtleties, he greedily seeks eternal years, renouncing birth in segments and stages and abruptly yearning for transformation, subtly contemplating permanent abiding. At that time the heavenly demon, waiting to seize its opportunity, flies its spirit to possess someone, who with his mouth preaches sūtras and dharmas. That person is completely unaware that a demon has possessed him, and likewise claims to have personally attained unsurpassed nirvāṇa; he comes to the place of that good person who seeks life, spreads a seat, and preaches the Dharma. He is fond of claiming to travel back and forth to other regions without impediment, or returning in an instant after traversing ten thousand li, always obtaining their objects from those places; or in a single place within one house, across a space of a few paces, he makes the person walk from the eastern to the western wall, yet though the person walks urgently, for successive years he cannot reach it. Because of this, his mind believes, suspecting that a Buddha has appeared before him."
