The Third Eye is the Seat of the Soul. It is the energy center between your eyebrows. Opening the Third Eye is often used in yoga, meditation, 
or other spiritual practices. 
It gives you a profound sense of spiritual connection and a greater understanding of your place in the universe.
The Third Eye also appears on the forehead of deities or enlightened beings, such as Buddha. It's a representation of higher consciousness—and it's believed to guide people in seeing the world with their minds.
