The Japanese Zen Buddhist practice of Kum Nye involves extreme running protocols with a high mortality rate.

“In Buddhism, and we were talking about this off camera, but there’s Japanese Zen, they’re the world record holders. They have this seven-year crazy, crazy, crazy running protocol training where at the end of it, people run more than 50 miles a day for 100 days straight. And many people die doing this, because they have to run carrying all their books, and they run in these crazy wooden shoes. Only 48 people have successfully done it since the 1850s. But why would you do this? Well, you do this because it’s believed to be a massive inducer of transcendent states. It’s a way to achieve Buddhahood in one lifetime.”
