Presenting vivid pictures of Gautama Buddha's life, teaching, suffering, death and subsequent nirvāṇa, the Mahāparinibbānasutta is one of the principal Buddhist texts. In Hermann Beckh's words, it describes '...one of the greatest human beings that ever lived, who stood at the threshold of the super-human – a teacher and leader of humanity.' Prof. Beckh's translation of this important sutta achieved a quality and faithfulness that was based on decades of extensive study and meditation. From his academic and spiritual knowledge, Beckh added insightful editorial material, including an introduction, commentary and notes. The English rendering here, by Indologist and long-standing Buddhist practitioner Dr Katrin Binder, is based on both the original Pālī and Beckh's German translation. An afterword by Thomas Meyer, informed by Rudolf Steiner's research, traces the development of Buddha's individuality in the afterlife. Departure of the Perfected One brings to a conclusion the publication of Beckh's great triad of works on the subject of Buddha, including Buddha's Life and Teaching and From Buddha to Christ. Through a contemporary reading, these books open up vast new perspectives on the world of sacred Buddhist scriptures to anyone interested in spiritual development.
