A moment is a span of time – to be precise the time it takes to move my weight from one foot to the other. If my attentions remain clear – unhindered by thought – at least for the duration of a moment then the heart will direct the energy in my body. The mind calculates and gauges and in doing so destroys creative impulse – energy – or weakens it to such a degree that it lacks the power to do anything of its own. The heart then remains locked up in the cage of the chest – safe but sad – unmoved.
