Book excerpt: Since the mind of every religionist of whatever faith, is firmly impressed with the superiority of his own creed, his mind is firmly closed to the truths of other beliefs. This is the root-cause of sectarianism and intolerance. Theosophists, instead of preaching they own religion, they implore everyone to first study his own and remain in it, whatever it is — for Theosophy is not only compatible with every religion, nay, being the pristine stream from the Mother-Source, it is the informing life and creed of all religions — pure and convincing in its simplicity. While modern science has no knowledge of an “Intelligent Being” or “Spirit,” the science of metaphysics rejects entirely the possibility of the Infinite having any relation whatsoever with the finite, whether conscious or otherwise.
