陀羅尼雜集 5.77

5.77

For three times seven days, abandon all mundane affairs and engagements, and before an image of the Buddha, during the six periods of the day and night, cast the five limbs to the ground and recite this dhāraṇī. Once the twenty-one days have passed, all heavy karmic obscurations of transgression since beginningless time will be completely extinguished without remainder, and one will attain entry into the first ground.
