A solitary mask dancer appears wearing a frightening mask and silk brocade. they circle the courtyard with sprightly leaps. called protectors of faith, or dharmapdla, the origins of figures like these can be traced back to the pre-aryan peoples of india. originally known as yaksas (literally, a wondrous thing), they were tree spirits, who were accepted by the buddhists as defenders of the faith. in nepal and tibet, as in india, local deities were converted into protectors. a devotee of an alien sect devised a means to humiliate the buddha and his disciples. the buddha discovered it and succeeded in converting him to his teaching. due to lack of wisdom, the buddha remarked, some could not realize the goodness of his disciples and he compared the ignorant to the blind and the wise to those who have eyes.nobody is condemned in buddhism, for greatness is latent even in the seemingly lowliest just as lotuses spring from muddy ponds. -the dhammapada. solu khumbu, nepal
