“Human beings [are] travellers… The earth is their matrix… [It is] but a station on their journey; for extraneous reasons… the travellers had interrupted their voyage… Human beings were caught in a sort of eddy, a current that went in circles, giving them the impression of moving while they were, in essence, stationary… Sorcerers were the only opponents of whatever force kept human beings prisoners… by means of their discipline sorcerers broke loose from its grip and continued their journey of awareness.”     — Carlos Castaneda, The Active Side of Infinity.
