Can a Buddhist monk do business? Can he do business successfully? Is there really a contradiction between spiritual practice and material enrichment? A practical answer to these questions is the life story of the author of this book, Geshe Michael Roach. Twenty years of persistent comprehension of Buddhism led him to obtain the academic title of Geshe - Master of Buddhist Sciences. Seventeen years in the diamond business allowed him to transform a small company with an initial capital of fifty thousand dollars into a transnational company whose turnover exceeded one hundred million dollars. The author of “The Diamond Cutter” believes that the goal of business and ancient Tibetan wisdom, as well as all human aspirations, is the same: to become rich, to achieve both external and internal prosperity.
