Za Rahula
Za Rahula (Skt. Rāhula; Tib. གཟའ་རཱ་ཧུ་ལ་, Wyl. gza' rA hu la) — one of the most important protectors of the Nyingma and Dzogchen teachings. He has nine heads, his upper body is covered with eyes, and the lower part is like a snake. When Longchenpa was writing the Seven Treasures at Gangri Thökar, it was Rahula who mixed the ink.
