勸發菩提心集 2.34

2.34

次教懺悔，懺悔訖歸依三寶。次云：「佛子已發大願，懺悔復訖，三寶歸已，三業清淨，真是如來法身之子，一切眾生法橋之主，至心頭面著地，攝持身心，隨語稱字。」

Next, [the master] instructs them in kṣamā; having completed the kṣamā, they take refuge in the Triratna. Next, he says: "Sons of the Buddha have already made the great vows, their kṣamā is also complete, they have taken refuge in the Triratna, and their three kinds of karma are purified; you are truly children of the Tathāgata's dharmakāya, masters of the Dharma-bridge for all sentient beings. Sincerely touch head and face to the ground, gather in and hold body and mind, and recite your names following my words."
