佛說觀佛三昧海經 9.23

9.23

The Buddha addressed Ānanda: "This buddhānusmṛti-samādhi is medicine for all sentient beings who commit transgressions, a protection for those who break the precepts, a guide for those who have lost the path, eyes for the blind, wisdom for the foolish, a lamp in the dark, a valiant general among the thieves of defilement, the playground of the Buddha Bhagavats, and the place from which the śūraṅgama and other great samādhis first arise."
