Look for the moment when grace intervenes. Do not, in ignorance, fail to intercept it, letting it pass by unheeded and therefore lost. There is a feeling of mystery in this moment which, if lingered with, turns to sacredness. This is the signal; seek to be alone, let go of everything else, cease other activities, begin not meditation but contemplation, the thought-free state.
