Once I asked Robert if OSHO were enlightened. He said yes. He hardly ever spoke of other teachers. Osho got a bad rap for numerous reasons.
However, the video below shows Osho demonstrating having much the same appearance as Robert: still eyes, still demeanor, and total involvement at the same time, and an apparent radiance of peace.
What he says is true, but coming to that understanding, and finding your way to that completely doing nothing state is very difficult. Osho created a hundred ways for his students to get there. The external trappings we all heard about are nothing. He knew it was nothing. It was his play.
