There is a place in everyone that can carry the light. God has made it this way. God has not only given us the chance to carry the light, but has made it possible for us to kindle and strengthen the light in one another, passing the light along. This way God's light will shine forever in this world.
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.
