All the religions existing at the present day have been founded during ages of ignorance, when we knew nothing about the earth or the heavens, True religion, i.e., the union of free spirits in the search for truth, can only be the work of an epoch like ours, in which some courageous and disinterested spirits free from the hypocrisy of false doctrines, yet without falling into the puerile atheism of superficial minds which see only the outer shell, will sincerely and freely apply all branches of science to the search for the intimate constitution of the universe and of the human being.

. . . we can consider the resources of Nature as infinite, and that "positive" science founded only upon our senses is quite insufficient, though it may be the only basis of our reasoning. It is through the eyes of the spirit that we must survey the universe.

Behind the visible world, our minds must feel the presence of the invisible world upon which we are based. All that we see is appearance: the real is the invisible, the force, the energy, which moves all and carries all through infinity and eternity.

The visible universe is not at all what it appears to be to our senses: it is the invisible universe which constitutes the essence and basis of creation.

The new physics is the proclamation of the invisible universe.

An invisible, immaterial element of a spiritual nature, as yet imperfectly revealed by our means of investigation, manifests itself within us and around us. The spiritual principle should be revered as enveloping the world and enfolding us.
