In this famous history of the sacred stūpa of Boudhanāth, Guru Padmasambhava recounts the stūpa's origins. In response to a request from King Trisong Deutsen, he tells how a humble poultry-woman first extracted a promise from the king and then built the stūpa together with her four sons, who were all later reborn as prominent figures in the introduction of Buddhism to Tibet. Padmasambhava also describes the benefits to be gained from circumambulating the stūpa and making offerings before it, and concludes with a series of prophecies concerning the stūpa's restoration.
