According to the Maya cosmology there is a finite amount of good in the universe, which is exchanged like a commodity from person to person, man to deity, and deity back to man. One way to receive good will from God is to make a an offering of good will — which often takes the form of a sacrificed animal, liquor, or soda combined with rhythmically chanting prayers and the lighting of dozens of candles. It is my impression that giving good is thought to create a sort of goodness vacuum which sucks good back to the pious worshiper. Often, I have read, that the Maya in Chamula are praying and making offerings to the saints/ deities for good health, good fortune in important life events, or to ward off evil will. I observed two chickens, countless bottles of pox and soda being sacrificed and offered during my visit, but, reputedly, dogs and cats are also occasionally brought in and killed all the same on the church floor.
