Nagualism: A Study in Native American Folk-lore and History
“ This [14] is not related to the Nahuatl tongue, but the terms of their magical rites are drawn from Nahuatl words, showing their origin. Every person at birth has assigned to him both a good and a bad genius, the former aiming at his welfare, the latter at his injury. The good genius is known by the Nahuatl term tonale, and it is represented in the first bird or animal of any kind which is seen in or near the house immediately after the birth of the infant.The most powerful person in the village is the high priest of the native cult. ”
