Here is the method: sense a spot of energy like a luminous clear-white ball slightly below the crown of your skull, centered between the ears but slightly higher, yet centered in between.
Close your eyes and sense that the little luminous sphere is the center of your Awareness. Notice how the sphere is itself Awareness. Be that sphere and just be. Concentrate on only that.
Notice the interior of your skull, as if it is hollow, remain with your eyes closed and sense a spacious clear light inseperable from your awareness.
Notice the crisp clearness of the interior light that offers a sensation of clear inner empty space.
You need to sense a dimension of spaciousness as luminous awareness. Practice with this exercise until you begin to sense that the solidity of your skull is becoming transparent and your sense of being a sphere of Awareness has become pronounced.
At that moment, just rest as that Awareness. The mind will have already vanished with all its thoughts and images... just rest in that Clear Light Awareness, that you are."
