According to Osho, there is no difference - because he refuses the label "godman." He says he belongs to no category; he is simply awareness, the same divine consciousness present in everyone and everything. Like Buddha's 'neti, neti,' he rejects all identities. His "I am God" means dissolving labels, not superiority. The invitation is to recognize your own watchfulness and live from that category-free presence.
I’m not a special holy man; I’m the same awareness you are—drop the labels and notice the watcher inside.
