WTH Are These Monks Doing?

I am going to preface everything you're about to read here with, I HAVE NO IDEA who these guys are, or what exactly this activity is called.

So, I'm going to speculate a little bit, and in the end...it really doesn't matter as this video is just epic no matter what we know.

It is posted by "Jampa Monlam," who by my research is some sort of exalted Asian monk.  Here he appears to be hanging with his bros in a competition that is sure to be stolen by fraternities everywhere.

Apparently, ENORMOUS logs are covered with rugs.  Then, the object is to summersault or cartwheel over the top of them.  Two observations here:  1.  As they're monks, these dudes are sober and 2.  This must be MUCH harder to do than it sounds.

Which takes me back to the fraternity speculation...if doing this is a chore sober...
