“Whenever we moderns pause for a moment, and enter the silence, and listen very carefully, the glimmer of our deepest nature begins to shine forth, and we are introduced to the mysteries of the deep, the call of the within, the infinite radiance of a splendor that time and space forgot – we are introduced to the all-pervading Spiritual domain that the growing tip of our honored ancestors were the first to discover. And they were good enough to leave us a general map to that infinite domain, a map called the Great Nest of Being, a map of our own interiors, an archeology of our own Spirit.”

—Ken Wilber, Integral Psychology
