Action is also psychological; it makes pictures in every atom of the body of the thought which is behind it. Every atom of the body prays, even the blood-cells; the whole being becomes a prayer. Thus the movements of the prayer are a psychological action. With every movement, we make as it were a kind of picture which impresses every atom of our body. This affects our circulation, and by the circulation the whole being is affected; it is even registered on the skin.
