Mahamudra and Atiyoga

Mahamudra and Atiyoga are particular forms of Buddhist spirituality : Mahamudra, the 'Great Seal', is considered by Tibetan teachers to be the essence of both the short path and the final instructions that conclude the gradual common and esoteric paths of Buddhist doctrines; Atiyoga of 'Extreme Union' represents the Buddhist Dzogchen or 'Great Completeness' doctrine.
