According to Osho, the ashram is controversial because truth inevitably shocks and shatters people’s comforting illusions; he refuses to compromise with societal 'stupidities' and challenges all forms of religious fanaticism, not just one tradition. Such uncompromising truth-telling provokes anger and resistance, naturally creating many enemies—and, by life’s balance, many friends—just as with Socrates, Buddha, and Jesus.
People get upset when their comfy beliefs are shaken, and Osho shakes everyone’s beliefs—so controversy happens.
