Ruben Feldman Gonzalez: "If you want to bring the Silence to the world , it's already gone" WHY? 

Purpose.. effort.. the illusion of the split of Reality (into subject-object) produced by thought, the horizontal conflict. It's a distortion of perception. But it's necessary to perform any action, to do something. That's why it (this mechanism of the horizontal split) evolved in the brain (by/with thought). 

So work/action has to be BALANCED with complete non-action in complete unobstructed Freedom/Peace, silence and stillness without any choice or effort. If not, the META Process with its horizontal split can drive one "crazy" bit by bit (e.g. fear, obsessions, stress, lack of sleep, desires, addictions, etc).

All of this, the very simple mechanism how the META process of thought produces this illusion of the horizontal conflict/split (so has to multiply division), is re-learned, re-discovered, has to be re-discovered in the brain, from the ground up. NOT in the books (only). Re-discovered over and over again, maybe from different points of view. But it happens all by itself for a monk (some one vitally interested in this) and this is correct, the best what can happen to any one.
