Duality, depicted here as a two dimensional male-female infinity symbol (made up of a male straight line and a female sinus wave or curve). Duality is necessarily a two sided coin. It is the principle of opposites like male-female, positive-negative, light-dark, full-empty, moving-still, etc. It is also also a symbol for physical existence (or manifestation) and non-existence as a spirit particle of the cosmic omni-verse (a drop in the ever moving ocean).
