Archetype and protector deities can have outer, inner, secret, and sometimes ultimate forms. The Outer Yamaraja, with his buffalo head, is the form normally represented. He confronts outer obstacles and seeks to protect practitioners and monasteries from doughts, bandits, and other misfortune.
There is also an Inner Yamaraja, a similar form usually represented with a human-type terrific face.
