The Four-Session Guru Yoga that we practice, composed by the Eighth Karmapa Miky Dorje, was based on an earlier guru yoga found in the writings of Lama Shangtsalpas (Lord Gampopas disciple), secret teachings that were sealed by command seal. Miky Dorje used this as the basis for his composition. There is a commentary on this practice written by the Ninth Gyalwang Karmapa Wangchuk Dorje, which is impracticably long. Chakme Rinpoche wrote his commentary because until that time there was no easily accessible commentary for doing Four-Session Guru Yoga. Chakme Rinpoche's commentary presents the meditations and visualizations to be done at the various sections of the text. Includes the sadhana of Four-Session Guru Yoga by Miky Dorje and a CD with Khenpo Karthar Rinpoche chanting the sadhana.
