According to Osho, the sixth body is the Brahman body where all duality dissolves: there is no I–thou, no inside–outside, no distance—and therefore no thought. One becomes cosmic; only direct knowing remains, not thinking. Thought ends because there is nothing “other” to relate to; what is, simply is, as pure, objectless awareness.
It’s when you feel one with everything, so thinking stops and there’s just clear, direct knowing.
