5. Reciprocal conjunction Every active principle, for the sake of conjunction, imparts from its own activity to a passive receiver, whence there results a reactive principle, and thereby conjunction. 1. The Lord alone is the active principle, man being passive; and in proportion as man receives of the active principle from the Lord, he reacts, and conjunction results thence. 2. Man's mind is the only active principle in the body, and in proportion as the body receives it, a simultaneous conjunction is effected. 3. Every muscle receives the active principle, and hence results action. 4. The heat of the sun is the only active principle in a tree, and it causes the tree to grow warm; and this warmth reciprocally conjoins itself, and action results hence. It is well known that every heated piece of wood sends forth warmth from itself; but when it is not heated, it cannot give out warmth. 5. From conjunction results equilibrium; and in this all action takes place.
