The same consciousness which was the monopoly of the vital and the mind has become that of the body: the consciousness is working in the cells of the body.
It is only by the progressive awakening of the Body's consciousness to the higher divine forces that it can eventually escape the law and need of illness.
... if you want to have a divine consciousness, you must not give up spiritual aspiration; but if you want to become an integral divine being on earth, take good care not to let go of the other end, and make your body the best possible instrument.
Nothing great is ever accomplished without endurance. If you study the lives of great men you will see how they set themselves like flint against the weaknesses of the vital.
Everything upon earth ultimately uses a physical pathway because that is how all manifestation takes place here. The hub of these pathways is the brain and the nervous system.
