Jetsunma Tamdrin Wangmo Kelzang Chokyi Nyima (1836-1896) was a highly accomplished female master of the Sakya tradition, born into the noble Khön family. She received extensive tantric training from renowned masters and was instrumental in preserving rare lineage transmissions, including Lamdre Lobshe and the teachings of the three "red deities." Upon returning to Sakya, she became a prolific teacher who transmitted empowerments and teachings to countless disciples, notably giving the complete Lamdre Lobshe twice and Vajramāla three times. Remembered as an emanation of Vajra Nairātmyā and Vajravārahī, she was accorded honours equal to male lineage holders and left a lasting legacy through her dedication to preserving Sakya teachings.
