Six Yogas of Niguma
Six Yogas of Niguma (Tib. ནི་གུ་ཆོས་དྲུག, nigu chö druk, Wyl. ni gu chos drug) — These six inner yoga practices originate from the Indian yogini Niguma and were transmitted to the yogini Sukhasiddhi and her Tibetan disciple Khyungpo Naljor, founder of the Shangpa Kagyü school. These six doctrines have the same titles as the Six Yogas of Naropa but differ in the details of how they are practised. These teachings were also transmitted from the Shangpa Kagyü tradition to the Gelugpa school. The second Dalai Lama, Gendün Gyatso, wrote a commentary to these six yogas called Detailed Instructions on the Six Yogas of Niguma (ནི་གུ་ཆོས་དྲུག་རྒྱས་པ་ཁྲིད་ཡིག, ni gu chos drug rgyas pa khrid yig).
