It seems to me that if God is love, He doesn't notice Fat Tuesday or Ash Wednesday because all He knows is love.
I think that the idea of guilt free eating plus 40 days of penance throws shit into the face of love. Now love doesn't care if you throw shit into its face. But how do you feel about it?
I mean why do you over indulge and then retreat into the desert alone with God, deep into the heart of Love? (A Biblical theme for Lent).
I agree with a life as steady as possible, without distractions, focused on Love everyday. Not just special occasions. And I also mean that one can have inner God focused peace even when the world seems in turmoil around you. This is what surrender (total self gift) achieves.
"Return to Me.....with all your heart...."
