Meister Eckhart told an analogy that speaks volumes to me. Basically, he said that if you take a basin of water or a mirror out in the sun, the sun will fill them with light. They will not only be filled with sunlight, but also reflect it. But, they will not be the sun, and the sun is still the sun and not diminished.
So too with the soul and God. God's Light shines there, but God is not diminished and is still everywhere. All is in God and God is in all.
It seems to me that our problem is that our reflecting out God's light can be dimmed or distorted by our choices. Just as my bathroom !mirror meed's to be cleaned so can see myself clearly, my soul needs to be cleaned of negativity, meanness, lack of integrity and so forth so that the pure Light of God can be reflected out.
It is our responsibility to get the log out of our eye and soul, to borrow an idea from Jesus. It's a life long process. Don't let that be daunting. Each day we strive ever toward the goal of being more and more Christ like.
