A single invocation of the Tibetan mantra: "Om Ah Hum Vajra Guru Padma Siddhi Hum". When you chant it, you are invoking the very embodiment of Padmasambhava. The Vajra Guru Mantra is the heart and essence of Padmasambhava. It is also the mantra of all the masters, buddhas, yidams, dakas, dakinis, and protectors. From wikipedia: Padmasambhava (Skt.), or Padmakara (Skt. Padmākara; Tib. པདྨཱ་ཀ་ར་, པདྨ་འབྱུང་གནས་, Pemajungné; Wyl. pad+ma 'byung gnas, in Sanskrit transliteration པདྨ་སམྦྷ་ཝ་) means ‘Lotus-born’, which refers to Guru Rinpoche's birth from a lotus in the land of Oddiyana. Guru Rinpoche, the ‘Precious Master’, is the founder of Tibetan Buddhism and the Buddha of our time. Whereas Buddha is known primarily for having taught the teachings of the sutra vehicle, Padmasambhava came into this world, and to Tibet in particular, in order to teach the tantras. While Buddha Shakyamuni exemplifies the buddha principle, the most important element in the sutrayana path, Padmasambhava personifies the guru principle, the heart of Vajrayana Buddhism, and he is therefore known as the "second Buddha".
I recorded this as a single take to check sound on my iPad, voice and guitar, an intro and one verse, then added a harmony vocal, single take, and slide guitar to for what I think of as Tibetan Mantra Blues. Then added three more voices in a semi-Gregorian style, with a cathedral reverb. All on a 9 dollar mike. You can hear soft rain and eventually early morning traffic here and there. Tracks are all improvised first takes in Garageband, then mastered in an ancient Wavelab program.
