'Early artistic depictions of the Buddhist khatvanga portray it as a sturdy skull-topped club with a short tapering shaft or leg, rather than the long, thin and delicate ritual implement portrayed in later Buddhist art. In the hands of Tibetan artists the vast majority of Indian weapons took on a much more refined and aesthetic quality and these weapons then became ritual objects depicted in the hands of deities.'
