Psychonaut. A "voyager into the soul," an apt term for the Buddhist adept, who voluntarily abandons the pseudo-security of this planet of delusion, with its solid ground of ordinary, individuated suffering, to launch herself through the death-dissolutions into the subtle between-states to deepen her wisdom by exploring the unconscious and to expand her compassionate heroism by serving universes of beings on the subtle level, and then returns to the ordinary embodiment of the adept to assist her contemporaries.
