Mahamudra is the principal meditation in the Drikung and other Kagyu traditions in Tibet. The Drikung Kagyu’s tradition of Mahamudra is called “fivefold” because in addition to the meditation on the nature of the mind, the term “great seal” (i.e mahamudra) is also used for bodhicitta motivation, yidam deity, guru devotion, and dedication of merit. Each of these indispensable five practices can be called Mahamudra in the Drikung Kagyu tradition.
This book by Drikung Lamchen Gyalpo Rinpoche is a thorough but easy to understand commentary on Kyobpa Jikten Sumgon’s “Song of the Fivefold Mahamudra” translated by Peter Alan Roberts.
