Visionary technology
Basic techniques used by shamans to achieve ecstatic states are varied and generally of simultaneous application. These include prolonged ritual diets, the ingestion of visionary plants, long periods of repetitive sound, dancing, chanting, and the creation and manipulation of objects imbued by helpers and allies. It should be stressed that the ecstatic experience is not the ultimate goal of the shaman, rather, it is the means through which specific objectives are attained; it provides a set of tools to understand the world.
