On the surface of this boulder we find a number of intriguing depictions. They include a mounted figure, a standing figure wielding a bow or spear, three dorjes (ritual thunderbolt of Vayrayana), concentric circles and two unidentified bi-circular designs. The bi-circular petrogylphs containing various design elements are the oldest figures on this boulder as indicated by the substantial repatination they have underwent (considerably more than the other figures). Recalling generative eggs, masks and mandalas, it would seem that they represent an important pre-Buddhist cultural theme by virtue of the subsequent carving of the dorjes on the same rock.
