The Shinto monks of Iso, Japan, have a curious custom. Every 20 years since the year 772, they've dismantled their central shrine and rebuilt it from scratch. In so doing, they pass down the knowledge of their sacred construction techniques from generation to generation. It's also an effective way for the monks to participate eagerly in the transitoriness of life, rather than merely being resigned to it. They practice the art of death and rebirth not just in meditation but through a practical long-term ritual.

I wonder if they use the same materials over and over. The new shrine different, and essentially the same.
