In today's world there is an attraction to martial arts with long and romantic histories. This is a selling point for many classical arts .... both real and fake. So I can understand ... but not condone .... why many teachers now claim things like 30 generations and that their school was founded by a tengu or whatever. But back in the Sengoku and Edo eras, why did koryu founders feel the need to embellish their lineages? What did it add? Surely back then the kind of people who studied koryu would be doing it PURELY for their effectiveness. Would the students really care about generations of lineage and mystical origins? I cannot imagine a samurai in the 1500s making a decision based on anything but effectiveness in battle. How will this training keep me alive? Did they really have the luxury of choosing something for its mystical and romantic history? So I am puzzled why Takenouchi Hisamori felt the need to invent a story about a yamabushi on Mt Atago breaking his bokuto ........ or why Izasa Choisai felt the need to spin a yarn about learning from angels ....... How would these embellishments have benefitted them?
