There is a saying in the Tibetan scriptures: 'Knowledge must be burned, hammered, and beaten like pure gold. Then one can wear it as an ornament.' So when you receive spiritual instruction from the hands of another, you do not take it uncritically, but you burn it, you hammer it, you beat it, until the bright, dignified color of gold appears. Then you craft it into an ornament, whatever design you like, and you put it on.
