"Non-dual anger is unconditioned clarity. It is displayed by the brilliance and calmness of water. The undisturbed surface of water perfectly mirrors the sky. The crystal clarity of undisturbed water seems incapable of bias or distortion. When water is clear it is barely visible - it seems to possess only the dimensionless reflective quality of its surface."
