The two biographies translated here are treasures revealed by Jamgon Kongtrul Lodro Taye, who was an emanation of the translator Vairochana, the subject of the second of the two biographies. Vairochana was a disciple of Guru Padmasambhava, the subject of the first biography. The purpose of these biographies is to inspire readers to vividly imagine the deeds of Guru Rinpoche and Vairochana, so they can appreciate those deeds and understand something of what such beings are. These stories are of people utterly unlike us in one sense and identical to us in another. However, because we have as yet not freed our potential from the limitations imposed on it by ignorance, our present state is very different from their present state. At the same time, seeing how extraordinary that achievement is can remind us that we have not yet realized our full potential. Therefore these stories are both uplifting and humbling.
