According to Osho, duality appears only in our reading of reality, not in reality itself. Truth is a single 'poem' with two readings: in sleep, we see a separate world; in awakening, the same world reveals the Divine. Nonduality is the fact; duality is a perspective born of half-awareness. Change consciousness, and the two become one.
Life is one thing, but when we’re half-asleep we see it as two; when we truly wake up, we see it’s all the same.
