Like all of Nature, humans develop according to universal patterns or archetypal forces. We know this as the “urge” toward growth. As complex material and spiritual beings, that urge takes place, not only at the material level as we grow into adulthood, but also at the mental and spiritual levels. To say it another way, the growth of the mind, body, and spirit is a natural unfolding of our potential.
