If by this superhuman concentration one succeeded in converting or resolving the two cosmoses with all their complexities into sheer ideas, he would then reach the causal world and stand on the borderline of fusion between mind and matter. There one perceives all created things — solids, liquids, gases, electricity, energy, all beings, gods, men, animals, plants, bacteria — as forms of consciousness, just as a man can close his eyes and realize that he exists, even though his body is invisible to his physical eyes and is present only as an idea.
