首楞嚴義疏注經 2.52

2.52

The Buddha said, 'Great King! Although your face is wrinkled, the nature of this essence of seeing has never wrinkled. That which wrinkles undergoes change; that which does not wrinkle is free of change. That which changes undergoes extinction; that which does not change fundamentally has no arising or ceasing—how could it undergo your birth and death within it?'
