the symbols of wholeness frequently occur at the beginning of the individuation process, indeed they can often be observed in the first dreams of early infancy. This observation says much for the a priori existence of potential wholeness, and on this account the idea of entelechy instantly recommends itself.
Jung argues that entelechy is, in certain conditions, more apt than ‘synthesis’ as a name for individuation, because wholeness-symbols appearing at life’s outset imply an a priori potential unfolding toward actuality.
