Do a little research on the Pineal Gland, what Witches call the Third Eye.
The pineal gland is occasionally associated with the sixth chakra (also called
Ajna or the third eye chakra in yoga) or sometimes the Seventh (Crown)
chakra. It is believed by some to be a dormant organ that can be awakened
to enable telepathic communication.
Writers such as Madame Blavatsky and Alice Bailey, considered early
proponents of the new age movement, use the pineal-eye as a key element in
their spiritual world-view...(see Alice Bailey: "A Treatise on White Magic",
Madame Blavatsky: "The Secret Doctrine")
