When you see the stars in the pitch black or dark blue sky, retreat to the back of the head slightly to the right side back near the inner ear.
From there look forward.
If you hear a high pitched frequency sound, listen to it as you peer forward.
If you man an attempt to pursue the star it will disappear. Therefore peer at it but do not make an attempt to control it or to make it stay where it is.
Sometimes during this practice the center of the forehead will open up and you will see into another environment. It will be as if your forehead has become a window into another world.
