<p><span>Santa Teresa is called in Cora Quemal&uacute;si, after the </span>[490] <span>principal one of the five mythical men who in ancient times lived in the Sierra del Nayarit. Reports say an idol now hidden was once found here. A few miles east of Santa Teresa is a deep volcanic lake, the only remnant of the large flood, the Coras say. It is called &quot;Mother,&quot; or &quot;Brother,&quot; the last name containing a reference to their great god, the Morning Star, Chulav&eacute;te. There are no fish in it, but turtles and ducks. The water is believed to cure the sick and strengthen the well, and there is no ceremony, in the Cora religion for which this water is not required. It is not necessary to use it pure; it is generally mixed with ordinary spring water, and in this way sprinkled over the people with a red orchid, or a deer-tail stretched over a stick.</span></p>
