"Documentary Religion," as Davis called it, was not in his opinion religion at all. That name could only be applied to the personal product of reason and spirituality. Such was the general line of teaching, mixed up with many revelations of Nature, which was laid down in the successive books of the "Harmonial Philosophy" which succeeded "Nature's Divine Revelations," and occupied the next few years of his life. Much of the teaching appeared in a strange paper called "The Univercoelum," and much was spread by lectures in which he laid before the public the results of his revelations.
