Sadly, the man, and mainstream people, just do not understand the mystic, and his/her revelations, are simply not hallucinations, but then, he is not a contemplative, but a drug user. He, and Andy Weil, (another drug user) have both confused the psychedelic experience with the mystical experience, which are only partially related, but they do not understand that the psychedelic can trigger an experience that is not unlike the mystic’s experience; but it is not the same thing. Only a mystic, who has taken psychedelic would know the difference.
