The state of the body is the state of body in its environment. Body makes its world wherever it finds itself and the contents of thought blend seamless with all the other elements of the setting, whether nominally in or out of the body. This is why travelling separates us from currents of thought that have become habitual. At best we become aware of the futility of all those contents revealed as merely ecological, expressions of faith in the continuity of life, of its process wedded to its context. A change in the physical circumstances of life comes about, or is understood to come about, by way of physical causality, which is an immensely complex web of explanations relying on transparent but infinitesimal concatenations of things. The adjustments of mind contribute nothing to the causality and yet are the essential response to its productions. The mind, always more or less impossible, excretes thought in order to maintain itself in the midst of this determinedly mindless process.
