Our culture, self-toxified by the poisonous by-products of technology and egocentric ideology, is the unhappy inheritor of the dominator attitude that alteration of consciousness by the use of plants or substances is somehow wrong, onanistic an perversely antisocial. I will argue that suppression of shamanistic gnosis, with its reliance and insistence on ecstatic dissolution of the ego, has robbed us of life’s meaning and made us enemies of the planet, ourselves and our grandchildren. We are killing the planet in order to keep intact the wrongheaded assumptions of the ego-dominator cultural style. It is time for change.
