This book is based on the author's multi-site and reflexive fieldwork on Mt. Apo where the Philippine National Oil Company built a geothermal power plant at the the heart of the country's remaining rainforest. The title itself plays around the double-meaning of physical energies from the bowels of the earth as well as cultural energies coming from a reawakened Obo-Manobo tribe who started its own cultural movement in the midst of the fight between development project and the political protest that arose against it. The author champions a verson of reflexive ethnography, which insists on the reality of the presence of the researcher in the field as well as in the resulting text. Detailed description makes this book an interesting reference for the study of social movements, environmental conflict, politics of rituals, body and society, development issues and indigenous culture, and the ethical complexity of fieldwork.
