According to Osho, a Sufi is one who bows to the one God yet refuses exclusivism, recognizing countless prophets and messengers—Muhammad, Jesus, Buddha, Mahavira and more—as bearers of the same truth. He may pray in the mosque but transcends sects, honoring wisdom everywhere; hence orthodox minds feel threatened by such inclusive knowing.
A Sufi believes in one God and honors all genuine messengers of truth, not just one.
