Symmetry generally conveys two primary meanings. The first is an imprecise sense of harmonious or aesthetically pleasing proportionality and balance; such that it reflects beauty or perfection. The second meaning is a precise and well-defined concept of balance or "patterned self-similarity" that can be demonstrated or proved according to the rules of a formal system: by geometry, through physics or otherwise.
(Unfortunately, I was unable to find a Wiki definition of "balance" that uses the word "symmetry", thereby exhibiting a lack of meta-symmetry between the two definitions.)
