The results presented here are part of fieldwork carried out over 40 years, from 1976 to 2016. The author lives in a community in central Yucatán (Tabi, Sotuta) and has carried out a number of research studies on Yucatecan shamanism in communities in the Mexican states of Yucatán, Campeche and Quintana Roo.
