陀羅尼雜集 10.53

10.53

此陀羅尼者，是除睡眠持行法。用十四日，若真舍利像前、若真塔前，種種香華白㲲縷二尋，誦一遍結一結，八百結。若欲不睡，繫著項上，悉得咸損眠。欲得睡時，岡下著淨處，燒香供養恭敬禮拜尊重讚嘆，諸天善神擁護是人。

As for this dhāraṇī, it is a method practiced to eliminate sleepiness. On the fourteenth day, either before true relics, an image, or a true stupa, using various fragrant flowers and two fathoms of white cotton thread, recite it once and tie one knot, making eight hundred knots. If one wishes not to sleep, tie it around the neck, and all sleepiness will be entirely reduced. When one wishes to sleep, remove it and place it in a pure place, burning incense, making offerings, reverently bowing, honoring, and praising it; all devas and benevolent deities will protect this person.
