佛說觀普賢菩薩行法經 1.24

1.24

「既見十方佛已，夢象頭上有一金剛人，以金剛杵遍擬六根；擬六根已，普賢菩薩為於行者說六根清淨懺悔之法。如是懺悔一日至七日，以諸佛現前三昧力故、普賢菩薩說法莊嚴故，耳漸漸聞障外聲、眼漸漸見障外事、鼻漸漸聞障外香。廣說如妙法華經得是六根清淨已，身心歡喜無諸惡相，心純是法，與法相應。

"Having seen the Buddhas of the ten directions, he dreams that on the elephant's head there is an adamantine person who points a vajra toward all six sense faculties. Having pointed it toward the six sense faculties, Samantabhadra Bodhisattva explains to the practitioner the method of repentance for purifying the six sense faculties. Repenting like this for one to seven days, by the power of the samādhi of the presence of all Buddhas and by the adornment of Samantabhadra Bodhisattva's Dharma teaching, his ears gradually hear sounds beyond obstacles, his eyes gradually see things beyond obstacles, and his nose gradually smells fragrances beyond obstacles. As broadly explained in the Lotus Sūtra, having attained this purification of the six sense faculties, his body and mind are joyous without any evil signs, his mind is purely the Dharma, and he accords with the Dharma."
