Mila was born in August 1051 in the tibetan village of Kyagnatsa in the province of Gung-thang (near the border with Nepal) and had a happy childhood. When he was seven, little after the birth of his sister Peta, his father got seriously ill and before dying he left his assets of peasant in usufruct to his relatives, until the boy came of age.

Although they had sworn to respect the dead man's will, immediately the uncles reduced Mila, his mother and his sister, to the condition of slaves and enjoyed the acquired assets for about ten years. When the time came to respect their oath, they denied the validity of the will and refused to apply it.

Not having any means to defend herself, Mila's mother, Karmo-kyen, sold the turquoise wedding ring and sent her son to learn black magic to have a revenge:

"I want you, after learning magic, to destroy first your uncle and your aunt, then the people of the country and the neighbours who have done harm to us."
