Look, it's simple.
Now we have our eyes on the screen, computer screen, tv screen, car screen, movie screen; on the flat screen of our thoughts or sight. What happens now if we bring our conscious attention back to its own source?...
It's easy.
First let's realize that we are not only aware of what is in front of us, or in us, but as well behind us, our back and the space around. Do not imagine, do not visualize. Sense it...
When awareness is brought back to the totality of its own field of attention, in the instant, what happens? What do you feel?... Experiment it...
We are aware of the totality of the environment included our body and what it comprehends, and over all, do not overlook,
We are aware of our Consciousness !...
