We use a top-down approach to explain physics of consciousness. We first focuse on the universe and propose a model discretization of the universe based on a T3-torus. An attempt is made to relate natural Planck units to the parameters of elementary geometric cells. We mention a way of approaching the horizon problem in discrete contest, as well. A suggestion for the discretization of the matter lagrangian part is also given. Then, by introducing a many-body method, we speculate on the binding energy in the very early universe and attempt to explain the source of a kind of dark energy that caused the inflation period. Finally, we focuse on the mind as a subset of the universe which is embeded in it and attempt to explain the source of consciousness as the "mind energy".
