陀羅尼雜集 10.53

10.53

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.
