According to Osho, what people call a 'title' is not something conferred or removable; 'Bhagwan/Osho' names a realized state of godliness, not an office or degree, so it cannot be dropped because it is his very being. Outer trappings like organization, robes, and malas can be discarded; only meditation and inner transformation truly identify his sannyasins.
Titles and clothes can change, but the real thing inside cannot; meditate and let that speak.
