ABSTRACT
Mental energy of all kinds, mind in every shape, needs a mechanism through which it can manifest itself, in this world at least. That mechanism is found in perfection in the human brain and is of extraordinary complication and delicacy. The largest part of the human brain, the most delicate and the most complicated portion, is devoted to this all-important function. All these functions of the brain are connected with each other in the most definite way. The fibres connected with those brain cells connect every unit and every group with each other and also connect them all with every organ and part of the human body. The brain requires and has an enormous blood supply. The large arteries come into the brain from different points, and at their base are connected in a circle, so that if one is accidentally blocked there are others to take its place.
