Indivisible oneness is the creative energy that turns a seed into a maple tree, or a watermelon or a human being or anything else that's alive. It's invisible, omnipresent, and absolutely indivisible. We can't divide oneness. Meditation offers us the closest experience we can have of rejoining our Source and being in the oneness at the same time that we're embodied. This means we have to tame our ego.
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.
