The oldest, the most profound, the most universal of all symbols is the human body. The Greeks, Persians, Egyptians, and Hindus considered a philosophical analysis of man’s triune nature to be an indispensable part of ethical and religious training. The Mysteries of every nation taught that the laws, elements, and powers of the universe were epitomized in the human constitution; that everything which existed outside of man had its analogue within man.
Manly P. Hall
"Philosophy bestows life in that it reveals the dignity and purpose of living. Materiality bestows death in that it benumbs or clouds those faculties of the human soul which should be responsive to the enlivening impulses of creative thought and ennobling virtue. How inferior to these standards of remote days are the laws by which men live in the twentieth century! Today man, a sublime creature with infinite capacity for self-improvement, in an effort to be true to false standards, turns from his birthright of understanding—without realizing the consequences—and plunges into the maelstrom of material illusion. The precious span of his earthly years he devotes to the pathetically futile effort to establish himself as an enduring power in a realm of unenduring things."
