金剛三昧經論 2.56

2.56

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."
