師子意菩薩曰。有漏無漏為二。若得諸法等則不起漏不漏想。不著於相亦不住無相。是為入不二法門　苦集有漏滅道無漏為二。大士平等觀同一實諦不二。什曰。師子度水要截流直度。曲則不度。此大士以實相智慧深入諸法直過彼岸。故借以為名。

The Bodhisattva Siṃhamati said, "The defiled (with outflows) and the undefiled (without outflows) constitute duality. If one attains the equality of all dharmas, one does not give rise to notions of outflows or absence of outflows, neither clinging to characteristics nor abiding in the absence of characteristics. This is entering the dharma gate of non-duality."
Suffering and origin are with outflows; cessation and the path are without outflows—these constitute duality. The mahāsattva contemplates them equally as identical with the one true reality, which is non-dual. Kumārajīva says, "When a lion crosses water, it must cut straight across the current; if it goes obliquely, it does not cross. This mahāsattva, through the wisdom of the true mark, deeply penetrates all dharmas and crosses directly to the other shore; hence he is named after this metaphor."
