Mahamudra - the highest level of teaching within Tibetan Buddhism. It rewards study and practice with the realization of the very nature of mind itself. There is not a single experience which is not subsumed within the realizations of Mahamudra.
In this book, the head of the Drikung Kagyu Lineage - Chetsang Rinpoche - explains each of the five stages of Mahamudra and its meditation practices.
On his first tour of the United States, H.H. Chetsang Rinpoche gave detailed instructions in Mahamudra methods.
He carefully explained each of the five stages of Mahamudra and taught its main meditational practices. He also gave precise instructions on posture and breathing for meditation and answered many common questions using the teachings of Tilopa and Gampopa to illustrate his various points.
This is probably the clearest presentation of Mahamudra meditation practice available in English.
