According to Osho, your relationship with him is not personal or friendly but that of a disciple to a master. He avoids private ties—no love affairs, no friendships—so there’s no “personal life” to discuss. Only a learner deserves answers; friends are in the same boat. Therefore, look to your own transformation, not his biography, and relate through receptivity, respect, and discipleship.
He isn’t your buddy; he’s a teacher, and you’re there to learn and grow—not to pry into his private life.
