Sometimes called the brow chakra, the third eye is located between and above the eyes. It is a a sphere of rich deep indigo. The third eye helps with many psychic endeavors since it governs the ability to see both the inner and outer planes of being. Its connected to your sense of thinking clearly, as well as your imagination, intuition, insight, wisdom and awareness. Not only does it help you make decisions, but helps differentiate reality from fantasy. If your third eye is exceptionally strong, you may have psychic abilities. Its lesson is understanding, reality check points, detachment and open mind.

Balanced Chakra
If your third eye is balanced, you will see yourself and your path in the universe clearly. You will have psychic abilities such as clairvoyance, telepathy, or perhaps even able to see ghosts and inter-dimensional beings.You will be very creative with a very healthy imagination. You may be open minded, and see your past, present and future very clearly. You will not fear death, and will not need another person to complete yourself.
