佛說觀佛三昧海經 2.47

2.47

“If there are those who wish to contemplate the Tathāgata’s eyes, they should perform this contemplation. Those who perform this contemplation will diminish all evils. Sitting upright with closed eyes, correctly contemplate the Buddha’s eyes for one to seven days, and in future lives they will always be able to see the Buddha, never be blind or plunged in darkness, nor be born in borderlands of wrong views where there is no Buddha-Dharma; their wisdom-eye will always be open, and they will not give rise to foolishness.”
