Harry Truman once said that listening to good music made him think of the way things ought to be, instead of the way they are. In the presence of music, we gain a taste of Heaven and Earth. Music is vitally important to our spiritual health: clearing the air, changing our mood, taking us to faraway places, revealing mysteries, calming the soul, allowing us true glimpses into the past.
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.
