Alienation on the other hand, is harmful to the survival of the system. With out complementarity there will be no inheritance of genetic replication. The examples of complementarity of yin and yang include the paradoxes of the matter and the mind, materialism and idealism, and the biological and the spiritual. Both are parts of the unity as in a ring. There is no moral priority of one over the other, for no point in a ring is before or after any other point.
Alienation is removed, but complementarity is preserved for life process.
Intrinsically, yin does not exist as purely yin, nor does Yang exist as purely Yang. There is yin in the yang, and yang in the yin. Yin and yang do not only complement each other, they are also inside each other. Yin influences yang not only from without but also from within. And yang influences yin in the same manner.
