Practice is everything; you practice to acquire facility in every art; but not one of these will repay you to the extent that the practice of joyousness will.Fall asleep at night, awaken in the morning; in the silence know, "All is joy." Then one day it will begin to work within you; you'll retain that joy as a permanent consciousness. Seek ye the realm of joy -- one of Love's holy attributes!
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.
