In a sense, the development of sophisticated religions in unconnected, disparate cultures suggests that there is something basic in the human psyche, that demands religion, or something in the human psyche that religion readily parasitizes
The text covers 14 years in the life of a Maya priest who lived in the eighth century A.D. It includes references to blood sacrifices and acts of penance preceding the spring solstice...Maya priests used manta ray stingers to pierce their earlobes, tongue, forehead, penis and other parts of the anatomy, in painful, bloodletting sacrifices to induce a hallucinogenic state in which they believed they could talk to their gods"
Somewhere in the human mind, there must be a common thread that connects the idea that blood sacrifices were practiced in the Middle East, and Europe, and ancient Mexico. . The Mayan dynasties were between 426 and 820 AD. By comparison to a religious timeline, in the West the Roman empire started to decline in about 410AD, and 570 - 632 was the life-time of Muhammad ibn ‘Abdullāh, the founder of Islam. (Wikipedia, Religious time line). Is this the same symbolism that leads modern religious leaders, and communities, to want the sacrifice of hated individuals or groups?
