The average man seeks certainty in the eyes of a spectator and calls it self-confidence. The warrior seeks to be impeccable in his own eyes and calls it humility. (Carlos Castaneda)

For the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life.
Leviticus, 17, 11
