Mankind is ever in need of truths which cannot, in every age, be wholly understood. The assimilation of truths is not only of significance for our knowledge. Truths in themselves contain life-force; and by permeating ourselves with truth, we permeate our soul being with a Cosmic element, 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 only understood much later.
