The energy we speak of is not qi (ch'i). In a sense it is spirit – pure and simple – but the spirit of uncertainty, of not knowing, of potential or possibility, the possibility, always, of something unaccounted or unexpected; the element of surprise. A person close to death – threatened by the drastic and irreversible – has such energy in abundance. New immigrants – especially illegal ones – have it: they wander and wonder in a daze of uncertainty. Children, especially babies, have it the most. It comes from being unable, or refusing, to discriminate or judge – unable to take support in anything that is not real. It is the power of powerlessness. All heart; or at least centred there.
