Yin & Yang
Yin and Yang are the interdependent forces of duality that make up the whole of existence. Light cannot exist without dark and dark cannot exist without light. All dualities complement one another and are necessary for the existence of their counterpart. Yin and Yang are also Solar and Lunar energy forces within the world and within our bodies. Yin is the manifestation of lunar (night) energy and Yang is solar (day) energy. Within the body, Yin is female energy and Yang is male energy. Yin and Yang remind us that everything that we think of and label as being a separate object is the sum of many interdependent parts working in tandem.
