Path work

Monks at Pongour Falls in Dalat, Vietnam by photographer Dang Ngo.

Known as the 7 Layers Waterfall, Pongour Falls is located just outside of Dalat (Lam Dong province) and is the largest waterfall in the region. The water drops about 30 meters (98.5 ft), and flows dramatically over 7 ‘layers’ into a big pool at the bottom.
Perhaps these layers connect to the 7 layers of Heaven? Or  to the 7 layers of the aura? Are these monks meditating as they come down? Is that even possible on a slippery path like this? Or ...?
