According to Osho, with sannyas everything changes from the inside: it is not a change of clothes but a radical reorientation, a new way of seeing and living. The old, anti-life renunciation is dropped. From this inner transformation, meditation—including Sufi methods—becomes a living, life-affirming exploration rather than an escape, flowering naturally within the new dimension of being.
After sannyas, you change inside, so any Sufi meditation you do comes from a fresh, life-loving heart instead of running away from life.
