Inner travel

         As the mind travels in and in, its frequency becomes subtler and subtler and consequently the force of the life-energy also correspondingly gets harmonised so as to regulate the functions the physical body, the brain-cells, the vibration-force of the life-energy and the frequency of mental wave are interconnected in their functions with one another. By self-action, chain-action and reflex-action, all the above four are getting corresponding changes in heir functions and characters by one another. When the mind functions only in the surface, its character is conditioned by the force of the physical and the brain-cells.
