In yoga, the third eye is referred to frequently in meditation as a means to encourage a connection with the Divine or Higher Awareness. The Bible says,
“When thine eye becomes single, the whole body fills with light.” ~ Matthew 6:22
In the yogic tradition, this "single eye" is the third eye, also known as the sixth chakra. When opened, you may have a deeper sense of knowing what is true--not because you read it or it makes sense, but you simply know in your heart. Inspiration and intuition stem from this energy center of the body. If you struggle with trusting yourself, work with asanas and meditations geared for this area.
Interestingly, balance poses are recommended to tap into the freedom and wisdom of the third eye. To be honest, I am not sure why. My best guess is that you have to be still and centered and trust in yourself in order to stand on one leg.
Be sure to add at least one balancing posture to your day and work with a teacher and great body awareness to level the hips somewhat while following a deep and steady breath. Allow the head to float skyward like a helium balloon. Enjoy the combination of rooting and "flying" at the same time.
Today is the first day of the rest of your life!
