Yogananda: Body is frozen thought…
Thought is the brain of the cells and units of Life Force present in every particle of bodily tissue. Hence, a disease thought upsets the entire government of the Life Force in the cells, whereas the thought of health corrects any disorder in the cellular system.
It must be remembered that I am speaking of the concentrated Divine Thought which can heal and not of the fanciful thought of imaginary people. In order to move Divine Thought, the ordinary man must know the relation of thought, Life Force, and body without denying the existence of the body thought. The body is the frozen thought and frozen energy of God. Nevertheless, man cannot realize this until he knows that thought is frozen into energy and energy is frozen into the body of man
– Paramhansa Yogananda
