Satrig Ersang (Tibetan: à ½¦à ¼Âà ½Âà ¾²à ½²à ½Âà ¼Âà ½¨à ½ºà ½¢à ¼Âà ½¦à ½Âà ¼Âà ¼Â, Wylie: sa trig er sang), also known as Yingkyi Yum Chemma or Sherab Chamma (Tibetan: à ½¤à ½ºà ½¦à ¼Âà ½¢à ½Âà ¼Âà ½Âà ½Âà ¼Âà ½Âà ¼Â, Wylie: shes rab cham ma), is a principal female deity in the Yungdrung Bön tradition of Tibet. She is revered as the embodiment of wisdom and is one of the Four Transcendent Lords, the highest deities in Bön cosmology.
Satrig Ersang, or Sherab Chamma, is considered the principal goddess in the Bön religion, ranking among the highest deities. She embodies wisdom and learning. She is often depicted seated with her legs tightly crossed and her hands at her heart, holding a mirror and a left-facing swastika (yungdrung) above her shoulders. These symbols represent wisdom and eternity.
In Bön iconography, she is usually depicted alongside the other three Transcendent Lords Shenlha Okar, Sangpo Bumtri, and Tonpa Shenrab Miwoche, forming a set of paintings, sculptures, or murals commonly found in Bön temples and shrines.
Satrig Ersang/Sherab Chamma is often portrayed seated on a lion throne under a throne arch, decorated with pairs of vases, dragons, boys, and makaras, at the apex of which is a garuda. The background of such depictions typically includes miniature representations of the goddess, symbolizing her pervasive presence.
In some thangkas, she is shown holding twin lotus stems supporting a mirror and a prayer wheel, flanked by attendants and surrounded by the 250 enlightened ones (sanggye), emphasizing her role as a central figure in the Bön pantheon.
Satrig Ersang/Sherab Chamma is believed to appear in various forms, each embodying different aspects of her divine nature. These include her role as a meditational deity akin to Saraswati, a deity of healing similar to Lakshmi, and a protector deity with a formidable appearance reminiscent of Durga or Kali.
