I don't know! Nobody has ever known. Why would Jesus have remained unmarried if he had known the secret? He knew the secret of the kingdom of God, but he did not know the secret of remaining happy in marriage. He remained unmarried. Mahavira, Lao Tzu Chuang Tzu, they all remained unmarried for the simple reason that there is no secret; otherwise these people would have discovered it. They could discover the ultimate - marriage is not such a big thing, it is very shallow - they even fathomed God, but they could not fathom marriage.
