To me? Some metaphysical thing, phenomenon, and/or dimension related to meaning and good. Mostly having little to do with religion.
Some thing taught me how to avoid cognitive dissonance. How? By avoiding lying (not speaking and mostly listening are essential). By avoiding thoughts of wealth, power, envy, righteousness, pride and other destructive influences. Getting your hands dirty and clean. Things that Jesus touched upon.
This thing also helped to come to terms with death, among other things. Most are scared to death of death and live/die accordingly.
