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.
We do not need to be experts or geniuses to remember that all of existence is precious. We do not need cathedrals to remind ourselves to experience the sacred. We need only to be deeply respectful of what is fundamentally true; and that is what we rediscover when we center ourselves in silence.
