Simhamukha (tib. seng ge dong chen kha dro ma) is a Wisdom Dakini. Her body is dark blue of color, three round eyes, blazing fiercely with a gaping mouth, and yellow hair flowing upward. The right hand holds upraised a curved knife to the sky, left a skullcap of blood to the mouth, carrying a khatvanga staff (tib. kha tvang ga) in the bend of the elbow supported against the shoulder.
From the three general divisions of Terma: Root, Branch and Essence, Simhamukha belongs to the Dakini Cycle within the Root Terma class.
