佛說觀佛三昧海經 2.47

2.47

「若有欲觀如來眼者，當作此觀，作此觀者減損諸惡。閉目端坐正觀佛眼，一日至七日，於未來世常得見佛，終不盲冥，亦不生於邊地邪見無佛法處，慧眼恒開不生愚癡。」

“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.”
