The Third Eye
The third eye refers to the 6th chakra (energy center) of the human body. It is located in the center of our head and is associated with the pineal gland that regulates the body's circadian rhythms. Many believe that when a person "opens" their third eye it allows for higher levels of consciousness, spirituality, thought, perception, self-reflection, awareness, wisdom, insight, and interconnectedness with all things in the universe.
It is known that the ancient Egyptians, Buddhists, Hindus, and many other philosophies from throughout human history regard the pineal gland as the seat of our spirit that brings about enlightenment, a higher consciousness, and spiritual awakening.
There are 7 chakras in total in the human body. When all of our chakras are "open", energy can run through them freely, and create harmony between the physical body, the mind, and the soul.
