Because the microcosm is identical with the macrocosm, it attracts the latter and thus brings about a kind of apocatastasis, a restoration of all individua to the original wholeness.
Jung argues that the alchemical microcosm-macrocosm identity is the metaphysical engine of transmutation, culminating in the restoration of the individual to the homo maximus or Anthropos, which is psychologically the Self.
