” This universe of ours, the universe of the senses, the rational, the intellectual, is bounded on both sides by the illimitable, the unknowable, the ever unknown. Herein is the search, herein are the inquiries, here are the facts; from this comes the light which is known to the world as religion. Essentially, however, religion belongs to the supersensuous and not to the sense plane. It is beyond all reasoning and is not on the plane of intellect. It is a vision, an inspiration, a plunge into the unknown and unknowable, making the unknowable more than known for it can never be “known”. This search has been in the human mind, as I believe, from the very beginning of humanity. There cannot have been human reasoning and intellect in any period of the world’s history without this struggle, this search beyond. In our little universe, this human mind, we see a thought arise. Whence it arises we do not know; and when it disappears, where it goes, we know not either. The macrocosm and the microcosm are, as it were, in the same groove, passing through the same stages, vibrating in the same key.”
