If all the openings of the head are closed you cannot move out, because you have always been moving out from these openings. You remain in, and with your consciousness remaining in it becomes concentrated between these two eyes, between these two ordinary eyes. It remains in between these two eyes, focused. That spot is known as the third eye.
Once you can feel inside this space between the two eyes, then you have known existence, the totality of it, because this inner space is all inclusive. Nothing is left out of it.
