“Mephistopheles' contentious, often ambiguous relationship to Faustus is a reference to tantra just as it is to alchemy. It resembles the shifting tactics of a guru who varies his approach to his pupil in order to dissolve his resistances and prepare him for wider states of consciousness. Both Faustus and the tantric aspirant stimulate and indulge their senses under the guidance of their teachers who encourage them to have sexual encounters with women in their dreams. Both work with magical diagrams or yantras, exhibit extraordinary will, "fly" on visionary journeys, acquire powers of teleportation, invisibility, prophecy, and healing, and have ritual intercourse with women whom they visualize as goddesses. The tantrist [sic] is said to become omniscient as a result of his sacred "marriage," and Faustus produces an omniscient child in his union with the visualized Helen, or Sophia.”
