No, that is untrue. The Force, which has been described as the combined vibrations of living things, contains both light and dark sides in its natural state ( according to Lucas, if it is not sufficiently self-evident that the aggregate energies of life forms would never be exclusively positive ). The balance is between the light and dark sides according to the OS. As such, neither one "is" balance; each balances the other. When the Force is out of balance it does not mean that the Force is out of light. "A family in balance. The light and the dark. Day with night." Here we have a manifestation of this in the day-night cycle on Mortis. Balance involves the presence of both polarities as opposed to being represented by only one ( all of one and none of the other is totally unbalanced ). Rebels presents essentially the same concept via the Bendu.
