Togden Zhang-gom Chöseng
Togden Zhang-gom Chöseng (rtogs ldan zhang sgom chos seng, 12th century). He was another important disciple of Khedrub Khyungpo Naljor. Though he did not receive the entire Shangpa Kagyu lineage transmission, as did Mokchokpa Rinchen Tsondrü, he is especially important in the lineage transmission of the teachings of the Six-armed Mahakala, the main protector of the Shangpa lineage. Togden Zhang-gom Chöseng had received teachings on the protector which Mokchokpa either did not receive or did not transmit to his main student and lineage holder Kyergangpa Chökyi Senge. Kyergangpa was however able to receive these instructions from Togden Zhang-gom Chöseng, and they continue to be transmitted to the present day.
