I am an ayahuasquero and regard myself as a shaman. This book is a study on Ayahuasca, the Amazonian ‘Vine of the Soul’ and one of the most ancient medicines known to man. The authors enthusiastically explore the history and tradition of this potent hallucinogenic plant brew, looking at traditions and shamanic or curandero practices in the lands where it evolved: Colombia, Peru, Brazil. The modern rise in cult popularity of Ayahuasca shamanism is explored. Apparently about 100 impromptu Western Ayahuasca ceremonies take place alone in New York City on a daily basis. The brew is used by the Santo Daime church of Brazil where Ayahuasca is taken as a sacrament. Laws are starting to break down regarding the illegality of DMT and other psychedelics and scientific research is being now supported by authorities. Ayahuasca has many implications for the healing of addiction, PTSD, depression and other psychiatric conditions plus has been reported to have cured cancers and AIDS. Charlatanism amongst shamans has been discussed and the popular Ayahuasca tourism industry in South America. Does Ayahuasca represent nature’s way of guiding us into dealing with the ecological catastrophe that is facing Planet Earth? The plant speaks and engages its human masters in realms unknown, where the jaguar and snake roam and ethereal otherworldly alien creatures engage in teaching us fundamental truths about our existence and survival. The plant, as it expands into Western societies reminds of of the rainforest from whence it came and can offer a new wave of spirituality to psychedelic adventurers that should surely benefit us all.
