to open your third eyes it not that easy to open . but here is my tips meditation. meditation is the big part of the third eye. image your third eye is opening up. by the way it does not work in the first try and bleave its going to work, and some way to train it get some flash cards with symbole and match them up like the matching up game. try to use it more.
One might add that you can practice all the time. Play a 'guessing' game with yourself when you can't practice traditionally. Anything works. The color of the next car to pass, or my favorite the next commercial to play on your favorite tv program.
