金剛三昧經論 2.56

2.56

經曰　「猶如淨甘露，時時乃一出，難遇難思議，聞者亦復難。無上良福田，最上勝妙藥，為度眾生故，而今為宣說。」

The sūtra states:
"Just like pure ambrosia,
Appearing only once in a while,
Difficult to encounter and inconceivable,
And those who hear it are also rare.
An unexcelled, fine field of merit,
The supreme, wondrous medicine;
For the sake of delivering sentient beings,
He proclaims it now."
