The Buddhist proverb, “The ultimate truth is not only hidden from you; it is actively being corrupted by your opinions,” reflects a key Zen teaching about perception and self-awareness. Rooted in the Hsin-Hsin Ming, traditionally attributed to Sengcan, the Third Patriarch of Zen Buddhism, the saying suggests that personal judgments, assumptions, and fixed beliefs can distort one's understanding of reality. The proverb encourages openness, humility, and mindful observation.
