Six Doctrines of Niguma
The six yogas of Niguma are almost identical to the six yogas of Nāropa but are the version taught by Niguma who was both a teacher and, depending on the sources, either the sister or spiritual consort of Nāropa. The second Dalai Lama, Gendun Gyatso has compiled a work on these yogas. Niguma transmitted her teachings to yogini Sukhasiddhī and then to Khyungpu Neldjor, the founder of the Shangpa Kagyu lineage. A translator and teacher in the lineage, Lama Sarah Harding, is currently working on a book about Niguma and the core role her teachings such as the six yogas of Niguma have played in the development of the Shangpa Kagyu lineage.
In the lineage of Machig Labdron, The practice of Mahamudra Chod begins with The Yoga of the Transference of Consciousness.
