One of the most important sadhana cycles in the Nyingma school of Tibetan Buddhism, the Rigdzin Düpa, or Gathering of the Vidyadharas, is practiced by tens of thousands of practitioners around the world. This inner guru practice focuses on Padmasambhava as the central figure and is one of the three root sadhanas of the Longchen Nyingtik treasure cycle revealed by the great Jigme Lingpa. This book will help readers mature their practice with invaluable instructions and commentary from some of the greatest Tibetan masters to have ever lived, including Patrul Rinpoche, Jamgön Kongtrul Lödro Tayé, and more. This book is for those who have received the reading transmission for the Rigdzin Düpa. Until such time as you receive the transmission, you can keep it on your shrine.
