I think about this line a lot. As I learn different skills, it feels like the route to deeper understanding follows the same path, even if that path winds through a different territory each time. I can apply a lot of the lessons I’ve learned in the past from cooking to improving my understanding of how to draw. I can apply some of the lessons I picked up in learning how to surf to improve my understanding of Taoism. Oil painting feels a lot like sculpting with clay or some other additive medium - the push and pull of it.
Recently I discovered that the master swordsman Miyamoto Musashi was also a recognized master artist, independent of his having used swords to kill tons of dudes. Peep this rad sumi-e painting of Kobokumeikakuzu -“Kingfisher on Withered Branch.”
In addition to painting, Musashi produced acclaimed masterworks in calligraphy, sculpture, and metalwork. Plus I guess he also wrote some books which wound up being pretty popular. He never received training in these fields, explaining that “When I apply the principle of strategy to the ways of different arts and crafts, I no longer have need for a teacher in any domain.”
