佛說觀佛三昧海經 6.23

6.23

佛告阿難：「汝從今日持如來語遍告弟子：『佛滅度後，造好形像令身相足，亦作無量化佛色像，及通身光及畫佛跡，以微妙彩及頗梨珠安白毫處，令諸眾生得見是相，但見此相心生歡喜，此人除却百億那由他恒河沙劫生死之罪。』」說此語已如來還坐。

The Buddha told Ānanda: 'From this day forward, uphold the Tathāgata's words and proclaim them everywhere to the disciples: "After the Buddha's parinirvāṇa, create fine images, making their bodily marks complete. Also make the physical forms of immeasurable transformation Buddhas, the light encompassing their whole bodies, and paint the Buddha's footprints; with exquisite pigments and crystal gems, place them at the site of the white curl, so that sentient beings may see this mark. Merely by seeing this mark and giving rise to joy in their hearts, such persons will eradicate the offenses of birth-and-death for a hundred billion nayutas of Ganges-sands kalpas."' Having spoken these words, the Tathāgata returned to his seat.
