To study angels is to shed light on ourselves, especially those aspects of ourselves that have been put down in our secularized civilizations, our secularized educational systems, and even our secularized worship system. By secularization, I mean anything that sucks the awe out of things.
The law of "thanksgiving" and gratitude is the divine law of multiplication. It is the law of bringing-forth, of creation, of increase. As the heavenly song of the universe pours into our beings in its complete fullness, we come to realize the purpose and the power of such infinite harmony. It is a song of love and devotion, of praise and exaltation, of gratitude and thanks that can clothe one in complete glory. It is the celestial symphony of the universe. It is the "new song" that is not learned in words, but which is felt and released from the very center of the soul. It is divine, perfected love, developed from within by gratitude.
