The third eye is a chakra point or a great energy focal point right above-between your eyebrows.

I don't really know the true meaning of "opening" it, but i have had some wonderful, enlightening experiences where I have been focusing on my third eye. I have only reached this point while meditating and letting my gaze drift up to the third eye, closing my eyelids and breathing very deeply and ... not thinking haha.

Its hard. But if you really want it, it is definetly there for everyone to tap into. It's beautiful!!

Love- Kate
