All human knowledge is conditioned by the fact of human relativity. Human nature, human intellect, and human egoism impose their limitations not only in material experience but also in mystical experience. Statements of divine truth made by mortal men should be read in the light of the fact that they are subject to such relativity. None is infallible, none eternally authoritative. Such seems to be the unhopeful situation. Is there then no way of disengaging the human agency from the divine message which manifests through it? The answer is that this way does exist and that its method is an intellectual as well as emotional purification, a moral and practical discipline, an intuitional and mystical preparation, and above all an elimination of the personal reference carried on incessantly through a long period.
