The Vajra Guru Mantra is the mantra associated with Guru Rinpoche, also known as Padmasambhava. This is a draft translation of a treasure text which explains the Vajra Guru Mantra. It was originally concealed during the time of Padmasambhava in Tibet and later rediscovered by Karma Lingpa (14th century) who brought it forth from its place of concealment and copied it down on reams of gold. It is simply known as "The Syllable by Syllable Commentary Explaining the Benefits of the Vajra Guru Mantra." It begins with an invocation and then goes into a dialogue between Yeshe Tsogyal, the spiritual consort of Padmasambhava, and Padmasambhava himself.
