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.
At first, even one minute spent in unaccustomed prayer will seem as endless as an empty silence or a blank stillness; but these periods of quiet can be lengthened profitably, and these times of silent stillness can become alive, eventually becoming the most rewarding experiences of the day, as one discovers how much God has to say to those who will listen. "In quietness and in confidence shall be your strength." A person who does not understand another's silences will not understand their words either.
