This class was filmed in Alonso's conservation area and retreat center "Bahuaja", located in the Peruvian Amazon jungle. All the sounds you hear are from the fauna and vibrant ecosystem which surrounded us during filming. For this class, Alonso talks from direct experience from his multiples encounters with Yubes and witchcraft, having himself been "cursed" by a group of Yubes, resulting in a crippling disease which lasted 7 years, the complete destruction of his house twice by natural disasters and several other tragedies. Alonso recovered from this curse by dieting and developing the healing framework he currently uses. All of this is shared in detail in "The four altars" book.
