According to Osho, Buddha and Shankara deny each other’s door—emptiness vs. fullness—not because the other is false, but out of compassion for confused seekers. A master can responsibly guide only along the path he has realized; insisting “only this” cuts through indecision, focuses trust, and gets you moving. Their refutations are pedagogical strategies, not metaphysical contradictions.
They say “only this way” so you don’t get stuck choosing; it’s to help you walk, not to insult the other road.
