Within the Eastern worldview, the human being is a microcosm of Nature, a smaller universe. Human beings represent the juncture between Heaven and Earth, the offspring of their union, a fusion of cosmic and terrestrial forces. The Chinese ideogram for human being is rooted like a tree in the Earth with hands outstretched like branches toward the heavens, receiving power from above and below. Sustained by the power of Earth and transformed by the power of Heaven, humanity cannot be separated from Nature-we are Nature, manifest as people. As a cosmos in miniature, we are propelled by the same forces. Good and bad are relative, not absolute. Life and death balance each other. Seen and unseen, soma and psyche, are aspects of one continuous process, by definition ever-changing and in flux.
