Not surprisingly, the young Minamoto, with much military tradition in his blood, did not take kindly to monastic discipline, and tutored himself secretly in the martial arts. Legend tell us that Yo****sune's instructors in the ways of sword-fighting were the 'tengu', small goblins - half men and half bird - who inhabited the mountains. You****sune used to slip out of the monstery at night and fence with these talented creatures. The tengu found him to be a promising pupil, and taught him numerous cuts and guards with te sword, as well as the use of a war-fan for defense, and, stranger still, how to fight with a tea-kettle!
