Krishna Yamari (Tib.: shin je she nag po. Eng.: the Black Killer of Death).
"He is the same as all the other [previous Yamaris], with three faces and six hands, the body and main face are blue, the right white and the left red. With six hands, the three right hold, a wheel, sword and staff, the three left, a body impaled on a strong vetali tree, vajra and noose." (Konchog Lhundrub, 1497-1557).
