According to Osho, the very desire to dissolve into the Master is still attachment—craving merely wearing a holy mask. It binds you to dependence and wandering, keeping you blind and time-bound. True union happens only when all wanting falls; the outer Master is seen as a mirror, the inner Master awakens, future-ache ends, time dissolves, and a self-luminous freedom flowers.
Wanting to merge with the Master is still wanting; drop all wanting through understanding, and you discover the Master inside you.
