God Has One Eye: The Mystics of the World's Religions

Mystics are not popular amongst the orthodox of any religion. In fact, almost every one of the religious leaders who founded world religions began their careers as mystics who spoke about what they had seen, and were promptly declared heretics. Just think of the Buddha, of Jesus, or of Muhammad. All of them were heretics, all of them were mystics, and all of them changed the way we view reality. Once the mystical vision hits you, you realize that everything you thought you were is a lie, that the universe you thought you were living in is gone, and that all the rules and structures by which you ordered your life are meaningless.
It is disorienting and painful. There is no lazy man's path to enlightenment, because once enlightenment hits, the lazy man no longer exists, and the luminous being which has taken his place is beyond recognition, even to himself.
