19. As light and shade and darkness and sunshine, bear no relation to one another; so the embodied soul has no connection with the body (in which it is thought to reside).
20. As the two contraries—cold and hot can never combine together, so the body and soul can never join with one another.
21. As the two opposites can have no relation between them, so is it with the body and soul, the one being dull matter, and the other an intelligent principle.
22. The dictum of the connection of the body with the pure intellect of the soul is as improbable as the subsistence of a sea in a conflagration (i.e., the impossibility of the meeting of water and wild fire).
23. The sight of truth, removes every false appearance; as the knowledge of light in the sandy desert, displaces the mirage of the ocean in the sun-beams.
24. The intellectual soul is immortal and undecaying, and perfectly pure and shining by itself; while the body is perishable and impure, and cannot therefore be related with the spirit.
25. The body is moved by the vital breath, and is fattened by solid aliments; and cannot therefore be related with the self-moving soul, which is without its increase or decrease.
26. The duality of the body (or matter) being acknowledged, does not prove its relation with the soul; and the dualism of material bodies being disproved, the theory of its relativity, falls at once to the ground.
27. Knowing thus the essence of the soul, you must rely on its subjective in-being within yourself; and then you will be free both from your bondage and liberation, in all places and at all times.
28. Believe all nature to be quiet and full of its quiescent soul; and let this be your firm belief, in whatever you see within and without yourself.
