In Liber CL (de lege libellum), Uncle Al riffs on Light, Life, Love & Liberty in relation to Thelema. He calls them the "rays" or "emanations of the law" of Thelema. During my first introduction to the Four Immeasurables it occured to me that we have a useful congruence here:

Love = Loving Kindness

Light [in Extension] = Compassion, because the "light hath healing in its wings."

Life = Joy, because "existence is pure joy."

Liberty = Equanimity, because freedom, or liberty, is the result of equanimity.
