The Glorious Sovereign Tantra of Mahākāla
The Glorious Sovereign Tantra of Mahākāla consists of a dialogue between Mahākāla and the Goddess on a broad range of topics including the consecration rites, deity generation practices, and rituals for attaining various siddhis associated with the deity Mahākāla. The opening section of the tantra focuses on topics related to the Unexcelled Yoga Tantras (yoganiruttaratantra, bla na med pa’i rgyud kyi rnal ’byor), such as how one generates the deity, how the consecration rites are performed, and how the advanced practitioner manipulates the vital winds of the subtle body to attain perfect spontaneous union as Mahākāla. The conversation then turns to ritual instructions for the attainment of siddhis as it integrates mastery of the two-stage union practices associated with the Unexcelled Yoga Tantras with those rituals more commonly associated with the Action Tantras (kriyātantra, bya ba’i rgyud) and Conduct Tantras (caryātantra, spyod pa’i rgyud).
