Guyhyanata Mahakala, Shanglon (English: Minister, Secret Lord Great Black One. Tibetan: nagpo chenpo, sang wai gonpo). Shanglon Dorje Dudul is a special protector associated with the Four Medical Tantras. He has three principal forms, outer, inner and secret. This painting depicts the mandala of the secret form of Shanglon Dorje Dudul including the retinue figures of all three forms of Shanglon in two concentric circles. A further group of eight figures in the outermost circle are the retinue to yet another form of Shanglon, riding a horse, where he is the protector of the Yutog Nyingtig Treasure Tradition, also associated with the Four Medical Tantras and the Tibetan physician Yutog Yontan Gonpo.

"...with a body blue-black in colour, three faces, black, white and red, bared fangs and hair flowing upward. With six hands the right three hold a trident, club and sword; the left three a skullcup, lasso and hook. [He] stands with the right leg extended pressing down on enemies and hindrances, dressed in an upper cloak of black silk, wearing felt boots, a jeweled crown, gold belt, together with a necklace of human heads, adorned with various ornaments, standing in a playful manner in the middle of a blazing heap of fire." (Jonang Taranata Collected Works, volume 15, page 728).

In the first circle immediately surrounding Shanglon, located in the four directions, are the principle retinue figures of the Secret form. Between the cardinal directions are four goddesses. In the outer circle, located in the four directions, are the four retinue figures specific to the Outer form of Shanglon. Between these four are four sets of paired deities which belong to the Yutog Nyingtig Treasure Tradition form of the protector Shanglon.

In the upper composition of the painting are the lineage figures in a direct teacher student line from Shakyamuni Buddha down to the time of the Nyingmapa teacher Terdag Lingpa Gyurme Dorje (1646-1714), the founder of Mindroling monastery.
