When you live life from your center, you operate from the indwelling spirit outwards into the visible world, like the spokes of a wheel, radiating God's love, wisdom and power. This is what is meant by being in the world but not of it. You remain calm in a crisis. You carry this calmness with you through the ordinary activities of the day, even when things go wrong... Centered in peace, you experience JOY... This is the culmination of growth in being. What you ARE, far more than what you say or do, will be the witness of your faith.
Dom Henri le Saux, a French Benedictine monk, suggests that the sacred sound "OM" can be used by anyone:
More than any particular name of Divinity, OM conveys the ineffability and the depths of the divine Mystery. It bears no distinct meaning ... It does not even recall any mythological or semi-historic event. It is a kind of inarticulate exclamation uttered when you are confronted with the Presence in yourself and around yourself.
You could say that OM is a name of God which is not a name.
