Guru Gampopa (1079-1152) was an important Tibetan Buddhist monk, guru, author, and transmitter of several Tibetan Buddhist lineages. Gampopa is generally acknowledged as the greatest disciple of Milarepa. Gampopa was at first a well known physician, following in his father's footsteps, and a husband and father. After the deaths of his immediate family, he became a dedicated disciple of Milarepa, and gained Enlightenment. Guru Gampopa became the "heart son" of Milarepa. It would later be the former's synthesis of Milarepa's meditative techniques and various doctrines of Tibetan Buddhism that would become the basis of the Kagyu tradition in Tibetan Buddhism. Guru Gampopa authored various treatises, and is perhaps best known for the Rosary of Precious Stones, included here in the 1984 Summer-Autumn edition of Studies. As in the representation to the left, he is usually depicted wearing a red hat and robes.
