Orgyen Tobgyal Rinpoche strongly recommends this text for those who wish to deepen their understanding of sur practice. In the text, Patrul Rinpoche describes in precise and graphic detail all the different types of guest that we invite to a sur offering. These descriptions are far more extensive than usually found in sur liturgies, helping us to generate devotion to those we invite out of faith, and compassion to the beggars, outcasts, fallen monastics and malevolent spirits who are the main objects of our offering. Patrul Rinpoche includes a special section for the spirits that held sway in his home region in Tibet—as Dilgo Khyentse Rinpoche wrote, “Kham was haunted in the past by many ghosts and evil spirits, and this was one of the reasons why Patrul Rinpoche used to explain the Bodhicharyavatara continually to his disciples. Before long, there were no more ghosts—or at least, no one came to any more harm. Such is the hidden power of Bodhichitta!”Dilgo Khyentse Rinpoche. Enlightened Courage. Snow Lion, page 29. Patrul Rinpoche’s compassion is evident throughout the text, particularly in his description of beggars who are devoted two sections. For each type of guest, we are instructed in how we should make offerings and what we should request of them. The text is an invaluable guide for Vajrayana practitioners.
