Sera Monastery, founded in 1419, is around 5k north of the Jokang Temple in Lhasa. In 1959, Sera was home to more than 5,000 monks. Although badly damaged, it's still in reasonable condition and home to now, only a few hundred Buddhist monks.
At the end of each day, the monks gather in the courtyard for the debating ritual. Monks take it in turn to be the sitting listener and the standing persuader. Essentially, they are debating the day's lessons learned.
