Mankind is always in need of truths which cannot, in every age, be wholly understood. The assimilation of truths is not significant only for our knowledge; truths themselves contain life-force. By permeating ourselves with truth we permeate our soul-nature with an element drawn from the objective world, just as we must permeate our physical being with air taken from outside in order to live. Deep truths are indeed expressed in great religious revelations, but in such a form that their real inner meaning is often not understood until much, much later.
