Kant and shamanistic journeying

According to Erich Rhode [On Hallucination, Intuition and the Becoming of "0"], who refers to the expertise of the psychoanalyst, Wilfred Bion, the psychological reduction of human experience to the contexts defined by space and time is a defence mechanism against knowledge (the gaining of which does not sit comfortably with the body’s sense of satisfaction) ( p 43):

The Kantian conception of experience as grounded in the grid of space and time is one of the systems by which mind defends itself against the impact of truth. People unable to use space and time as modes of defense, who keep slipping out of the skin of being a personality in “their own day and age” are most prone to catastrophic change and possibly to be creative.
