In 1986, seven "former devotees" filed a fraud suit against the Maharishi saying they paid thousands of dollars for lessons at Maharishi International University that were designed to reduce stress, improve memory, reverse aging, and develop clairvoyance and levitation. One plaintiff said that after ten years he had not acquired any of the special abilities that were promised. According to reviews of the 1992 book, "Heaven on Earth – Dispatches from America’s Spiritual Frontier", author and reporter Michael D'Antonio wrote that the MIU physics department was teaching theories that he believed were "dead wrong" and alleged that the university had taken Transcendental Meditation "into a grandiose narcissistic dream, a form of intellectual bondage, that they call enlightenment".
