華嚴經金師子章註 1.39

1.39

色者悲也，空者智也。觀色即空，成大智，而不住生死；觀空即色，成大悲，而不滯涅槃。能辯之智煥然明了。

Form is compassion; emptiness is wisdom. Contemplating form as emptiness completes great wisdom, so that one does not abide in birth and death; contemplating emptiness as form completes great compassion, so that one does not linger in nirvāṇa. The discriminating wisdom is brilliantly luminous and clear.
