法眼的關鍵真言

Then Ven. Assaji gave this Dhamma exposition to Sariputta the Wanderer: 

Whatever phenomena arise from cause: their cause & their cessation. Such is the teaching of the Tathagata, the Great Contemplative.

Then to Sariputta the wanderer, as he heard this Dhamma exposition, there arose the dustless, stainless Dhamma eye: "Whatever is subject to origination is all subject to cessation."

Even if just this is the Dhamma, you have penetrated to the Sorrowless (asoka) State unseen, overlooked (by us) for many myriads of aeons.

Then Sariputta the wanderer went to Moggallana the wanderer. Moggallana the wanderer saw him coming from afar and, on seeing him, said, "Bright are your faculties, my friend; pure your complexion, and clear. Could it be that you have attained the Deathless?"

"Yes, my friend, I have attained the Deathless. "

Mv 1.23.5-10 by Thanissaro Bhikkhu

時，具壽阿說示為梵志舍利弗說此法門：

  諸法因緣生

  如來說其因
  諸法滅亦然
  是大沙門說

時，梵志舍利弗聞此法門，得遠塵離垢法眼，〔謂：〕

  凡有集法者

  皆有此滅法
..........

時，梵志舍利弗至梵志目犍連處，梵志目楗連見梵志舍利弗從遠方來，見而言梵志舍利弗曰： 

汝諸根澄清，汝膚色清淨、皎潔。汝得不死否？

〔梵志舍利弗曰：〕

然！得不死矣。
