In the final analysis meditation is a love affair. And love is the most powerful energy in the universe. The great irony of meditation is that we become more immersed in the here-and-now. We are liberated from our false egos, and begin to know and love others at a deeper level of awareness. Liberated from our possessiveness, we reach out with a new found compassion to our family, friends, and the less fortunate.
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.
