Good and interesting question.
The third eye, or mind’s eye, is the 6th chakra located on your forehead. Discussed in Buddhism, Hinduism, Taoism, and other belief systems, It is at the location of the pineal gland. It is a divine connection to the source, and is believed to allow one to perceive more than what can be seen through physical sight. It is a doorway to higher conciousness, which can be opened or awakened through meditation, yoga and other practices that focus on opening the third eye. Artwork: Alex Grey, COSM
