An energy network is conducted through and around the body which is connected and coordinated from the main center in the head. The center in the head controls the energy of the body and pulls it towards itself and gives it over to the external system with which it is connected. The external system is everything with which you come into contact – other bodies, technology, ... Also, that center produces thoughts which are inserted into the body. Generally, it's the center through which the Matrix system exhausts every individual, controls and leaves him/her with minimal amount of energy. This is the explanation why no one is in the body. What has been done is that the human thinks that the main driving center is the brain, and not the Heart. And as long as it is so, he doesn't have the power over himself because with each thought, action, state, ..., he gives over his energy to the external system which is getting stronger and more controlling and imposes its rules. Personality and originality disappears. Installations in the head eject the energy from the body into space. That energy mass is a state produced by the human. It smothers the space, atmosphere and thus creating ecological pollution. When the main center of the body becomes the Heart, everything will go into the Black hole and from the Black hole which means that it's pure. This is true ecology.
This is just another way that explains the relationship and addiction of the Matrix and the human and vice versa. Without the Center Heart, a human has no information about reality nor who he is. He seeks all answers outside of himself and therefore almost everything he produces, he gives outside of himself. That's why he is mortal and insufficient.
The second part of the story is: there is a predatory race that has built their entire existence based on energy (=information) which were originally owned by human. The human surrendered the technology with which he is now subjugated. This should be more than enough reason to start a war for the Heart and with the Heart.
