佛說觀佛三昧海經 2.26

2.26

「佛滅度後諸四部眾，若能暫時捨離散亂，繫心正觀菩薩降魔白毫相者，滅無數劫黑業惡障，亦除十惡諸煩惱障，能於現世見佛影像了了分明，如是種種觀相境界不可具說。

"After the Buddha's parinirvāṇa, if members of the fourfold assembly can temporarily set aside distraction and focus their minds to correctly contemplate the mark of the Bodhisattva's white curl when subduing the demon, they will extinguish the dark karma and evil hindrances of countless kalpas, eliminate the afflictive hindrances of the ten evils, and be able in their present life to see the Buddha's image clearly and distinctly. Such various realms of contemplating the marks cannot be fully described.
