Ratnasambhava
Shavaripa was an Indian Mahasiddha who figures prominently in the early lineage of the Mahamudra transmission. Nothing much is known about him. Apparently he was a hunter who was dissuaded from his evil livelyhood by Avalokiteshvara himself. The Bodhisattva appeared to him and boasted of being the better hunter of the two. He challenged Shavaripa to a competition and said he could kill 100 animals (which were his own emanations) by shooting a single arrow, which he proceeded to do. Shavaripa could not compete. Avalokitishvara then showed Shavaripa the hell reamls in which he would be reborn in the future. Terrified, Shavaripa abandoned hunting altogether.
He later met the Mahasiddha Saraha and the incomparable Nagarjuna, from whom he received Mahamudra instructions. He practiced these and attained complete realisation. Shavaripa then passed these instructions on to his disciple Maitripa.
