In a sense, the state of presence could be compared to waiting. Jesus used the analogy of waiting in some of his parables. This is not the usual noted or restless kind of waiting that is a denial of the present. It is not a waiting in which your attention is focused on some point in the future and the present is perceived as an undesirable obstacle that prevents you form having what you want. There is a qualitatively different kind of waiting, one that requires your total alertness. Something could happen at any moment, and if you are not absolutely awake, absolutely still, you will miss it. This is the kind of waiting Jesus talks about. In that state, all your attention is in the Now. There is none left for daydreaming, thinking, remembering, anticipating. There is no tension in it, no fear, just alert presence. You are present with your while Being, with every cell of your body. In that state, the “you” that has a past and a future, the personality if your like, is hardly there anymore. And yet nothing of value is lost. You are still essentially yourself. In fact, you are more fully yourself than you ever were before, or rather it is only now that you are truly yourself.
“Be like a servant waiting for the return of the master,” says Jesus. The servant does not know at what hour the master is going to come. So he stays awake, alert, poised, still, lest he miss the master’s arrival.
