Why is Zen called the path of paradox?

According to Osho, Zen is called the path of paradox because reality is woven of complementary opposites—like bricks facing each other forming an arch—so true religion must speak through contradiction. Zen uses startling, non-linguistic shocks and koans to bypass logic, collapse the mind’s sleep, and ignite pure awareness. Paradox doesn’t confuse; it fuses life and death, monk and layman, into direct seeing beyond concepts—hence Zen’s strange, liberating methods.
