Regional Example The Willamette Valley's river bottom is Yin relative to the Cascade Range peaks; yet the Willamette Valley is Yang with development relative to quietude of the Cascades. Hence a favorite retreat for Taoist souls is contemplative meditation on high remote peaks for the Yin nature within Yang; or the Yang within Yin. A challenge for the urban dweller is to reflect upon Yin nature within Yang city activity. Top

Therefore having and not having arise together, Difficult and easy complement each other. Long and short contrast each other. High and low rest upon each other. Voice and sound harmonize each other, Front and back follow each other. Lao Tzu, TaoTeChing, Chapter 2
