The Great Chant of Shamanism is a work written by a Master and artist of power. A delight of music and poetry following the trends of the enchantments and teachings of ancient times. In this work the origin of disease is explained, but also the internal conflict and the consequences in the world of the separation from Arutam, the final healing, and the true meaning of the shamanic way. Although this is an open text for any spiritual culture, a more Amazonian meaning has been chosen at the end of the book by introducing Ayahuasca as the personal choice in this occasion. This is a work of priceless value for humanity since it is very rare for a shaman to write in detail and deliver medicine in each sentence. The art of shamanic spirituality has always been transmitted from Master to student orally, or in the silence of feeling and deep vision. The traditional ways of power transmission are: ceremonies, initiations, whispers, master plants, medicines, magnificent chants, art... but the needs of the world and the increasing human misery have made the vision of this manuscript possible. Arutam Ruyman (Ruyman Barcelo Solano) is a Master of proven experience thanks to his long-term work around the world. Largely trained in the traditional way, initiated and recognised with the highest honours by the members of the Elder-Shamans of the Shuar tribe from the Amazons, particularly the tribe chief Jimbikit. He becomes a Master, healer and prominent spiritual leader amongst tribesmen and men all over the world. His art prides itself in a millenary inheritance, its realization is constantly evolving, because it flows from his Union with Arutam which he cares for with dedication. The Masters during his youth, his natural curiosity, and his ability to understand as a result of his spontaneous maturity, have led him to mastered many types of shamanic transmission as well as the use of medicinal and master plants of very diverse nature. His background as a master of Traditional Chinese Medicine and his studies of Psychology, makes this a more approachable work for the general reader, and allows us to understand a large unknown part of the real ancient shamanism. His teachings arise from the most profound understanding and his art of transmission from Arutam, through singing and music, have powerfully set in the hearts of many people throughout the world."
