The highest level of prayer is not a prayer FOR anything. It is a deep and profound silence, in which we allow ourselves to be still and know God. In that silence, we are changed. We are calmed. We are illumined. Prayer is meant to dissolve the worldly focus, to dissolve our sense of a separate self, to help us detach from the noisy world order.
Prayer is like pouring hot water on an ice cube, melting the cold and encrusted thought forms that still surround our hearts.
Silence is powerful; it must be approached with sensitivity. There are times when silence during a meal may be important, while at other times it may be a hindrance. Silence at meals is interesting to explore; many find it increases the energy obtained from the meal. But beware. A little silence in a noisy culture is revolutionary; you may learn to love it. If that happens, share your silence with those who also love silence.
