Niguma (11th c.) was the **Indian female mahasiddha** — sister or consort of the great Indian master Naropa — who **transmitted the Six Yogas of Niguma that became the foundation of the Shangpa Kagyu lineage of Tibetan Buddhism**. **Believed to have already attained full enlightenment (the Rainbow Body) by the time she taught**, she remains a luminous figure of female enlightenment in Vajrayana.
Featured throughout Shangpa Kagyu lineage texts.
Niguma reduces to five — the number of Shangpa Kagyu foundress.
