yin-yang
                over a period of hundreds of years Chinese
                mystics and religious described the cosmos
                in a variety of terms. whether attempting to
                define an origination or merely reflecting on
                their insights, some found value in a bipolar
                description, focussing on the two components:
                Yin and Yang. typically, Yin and Yang are
                ascribed categorical associations of qualities
                which may be presumed to partake greatly of
                one pole of this energetic pair. Yin is often
                described as feminine, dark, cool, low, restful,
                yielding, and moist. Yang is comparably
                provided the description of masculine, bright,
                warm, high, active, forceful, and dry. phenomena
                are attributed greater quantity of Yin or Yang
                depending upon their specific qualitative and
                experiential nature. for example, the Sun is
                described as predominantly Yang, while the Moon
                is considered more Yin in nature. mountains are
                described as Yang, while valleys are Yin. this
                bipolar relation is sometimes correlated or
                compared with a system of 5 Elements that some
                presume to resemble those described by Aristotle
                (the Chinese have Water, Wood, Earth, Metal, and
                Fire; while Aristotle's were Air, Earth, Fire
                and Water).
