The familiar Hebrew word shalom, usually translated as “peace,” means more than the absence of quarreling. Shalom means wholeness, everything fitting together, nothing missing and nothing broken. Just as peace on the world scene means no fighting between nations, no quarreling with other people, shalom for you as an individual means no fighting with yourself, no quarreling between two halves of a divided soul. To wish someone shalom is to with [them] the blessing of wholeness and integrity.
