In general, Buddhism is not overly concerned with the direction the svastika turns. This is not true for the Bon religion, however, where the left-turning yungdrung is the principal symbol of the religion, and a right-turning yungdrung has no meaning. The word is also part of the official name of the religion, Yungdrung Bon or 'Everlasting Truth'. The yungdrung is also a commonly found in the hands of Bon teachers and deities in a variety of shapes, colors, and sizes. It is even used for religious hats and seats, carpets, and for marking the bottom of Bon sculpture. Since ancient times, the yungdrung has been one of the more common etchings in pictographs and petroglyphs of the western Himalayas and Tibet.
