Sacrifice for suffering humanity. Loving-kindness towards all beings. One of the three primary factors for spiritual development.
"Charity is a matter of common sense. To give food to the hungry is something very humane, because even the prisoners have to eat, otherwise they would die of hunger. To give drink to the thirsty is something very logical, since it would be cruel to deny a glass of water to a thirsty person. To give a shirt to the naked is something very natural; to console the afflicted one is very humane; so, we do not needed judges for that. Nevertheless, it would be an absurdity to give alcohol to the drunkard, or to lend a weapon to an assassin. Love is law, but love with cognizance!" - Samael Aun Weor, Beyond Death
