The third eye (also known as the inner
eye) is a metaphysical and esoteric concept referring in part to the
ajna (brow) chakra in certain Eastern and Western spiritual traditions.
It is also spoken of as the gate that leads within to inner realms and
spaces of higher consciousness. In New Age spirituality, the third eye
may alternately symbolize a state of enlightenment or the evocation of
mental images having deeply-personal spiritual or psychological
significance. The third eye is often associated with visions,
clairvoyance, precognition, and out-of-body experiences, and people who
have allegedly developed the capacity to use their third eyes are
sometimes known as seers.
