While over the years I have been able to reconstruct a few portions of the Kumeyaay religious beliefs, the occasion for discussing my fragmentary reconstruction had not occurred. To discuss these matters under ordinary circumstances would be to cause someone's death. Thus, passage of the National Environmental Policy Act and the Native American Religious Freedom Act, which provided the opportunity to protect the sacred mountain, Kuuchamaa, presented the opportunity opportunity to develop a more complete and correct understanding of the moralistic and mystical philosophy of the Kumeyaay religion. Further, the Kumeyaay elders, having become aware of the published descriptions of their society and their religion and desiring that more correct information be presented, have asked that this material be published.
