When I travel in Bhutan, there were plenty visits of monasteries and temples. One day on our tour, we met some monks building new stupa and they have invited us to see and photograph their brothers in nearby monastery. It was Buddhist college Gangtey Shedra and we had great opportunity to experience prayers.
Young boys of 5-6 years join monastery to learn how to read, write and use ritual things. Their days are devoted to prayers and self-study.
