I watched that on Amazon Prime Video, it was good. Some years back 60 minutes did a two part report on Mount Athos, it was also great, it's on youtube. Before I Pass on, I would like to visit Athos, I wanted to visit when I was stationed in Greece, but could never get it together. I would also like to visit Ostrog, and Sumela.
I just watched this and enjoyed it. My favorite part was when one monk received a package from his sister containing new shoes for his knees and four pairs of socks, and he offered a pair of socks to his fellow monk, who then asked if he could have two pairs, and the monk immediately said, of course, take them, they are yours. A great example to us all.
