This is not specifically about Aikido, but what resonated with me was the life-changing potential in finding the right teacher, your teacher, in whatever it is that you do, and honoring your duty to pass the art along.
Plus it’s a beautiful video. It’s about Michael Bell, master swordsmith of Dragonfly Forge and head instructor of Tomboyama Nihontō Tanren Dōjō (Dragonfly Mountain Japanese Sword Forging School). Enjoy.
