佛說佛名經 19.54

19.54

「舍利弗！若比丘、比丘尼、優婆、塞優婆夷，欲懺悔諸罪，當淨洗浴著新淨衣，淨治室內敷設高座安置佛像，懸二十五枚幡，種種華香供養，誦此二十五佛名，日夜六時懺悔，滿二十五日，滅四重八重等罪，式叉摩那、沙彌、沙彌尼，亦復如是。」

"Śāriputra, if a bhikṣu, bhikṣuṇī, upāsaka, or upāsikā wishes to perform kṣamā for their various offenses, they should bathe cleanly, don newly cleaned robes, clean and purify the room, arrange a high seat, set up an image of the Buddha, hang twenty-five banners, offer various flowers and incenses, recite the names of these twenty-five Buddhas, and perform kṣamā through the six periods of the day and night. When twenty-five days are complete, offenses such as the four grave offenses and eight grave offenses will be extinguished. For śikṣamāṇās, śrāmaṇeras, and śrāmaṇerikās, it is also likewise."
