Transcendence (rising above), enlightenment (obtaining the inner light), extinction of the self (the self being one’s “fake personality” imposed by the material world), apotheosis (transformation into a divine or semi-divine being), gnosis (possessing the transformative insight), producing the philosopher’s stone (a metaphysical possession that "transmutes lead into gold"), gaining entrance to heaven and so-on, these all arguably refer to the same thing or intimately connected things.
