I have the text and CD recording of the Cedrub Gondus of Nyala Pema Dundul (aka Long life Practice of Guru Amitayus). The practice only includes Rinpoche singing the last of the three invocations. Has anyone had any experience with practice? At least enough to tell me whether the tunes for the other two invocations are the same as for the last one? Or otherwise, where I can find an MP3 of the other melodies?
