Nearness to God is dependent upon purity of the heart and exhilaration of the spirit through the glad tidings of the Kingdom. Consider how a pure, well-polished mirror fully reflects the effulgence of the sun, no matter how distant the sun may be. As soon as the mirror is cleaned and purified, the sun will manifest itself. The more pure and sanctified the heart of man becomes, the nearer it draws to God, and the light of the Sun of Reality is revealed within it. This light sets hearts aglow with the fire of the love of God, opens in them the doors of knowledge and unseals the divine mysteries so that spiritual discoveries are made possible.
