There used to be thousands of monasteries in Tibet. Every family was expected to send at least one boy to a monastery. Usually, boys would be ordained at the age of seven; girls, a bit older. The monastery life used to be the only access to education and improved social status. People went to monasteries to get educated, to merit their family and to pursue religious fulfillment. Although educational and economic conditions in Tibet have improved, many Tibetans are still drawn to the monasteries.
The monastery life is rigorous. Monks are involved in all kinds of religious services and administrative tasks, on behalf of individual study and the monastery community. Daily life starts in the early morning and ends in the late night. The whole day is occupied with communal or individual religious services and the management of the monastery. Older monks, learned lamas, hold greater responsibilities such as maintaining discipline and leading the group prayers. Younger monks help by running the kitchen, shopping and serving food and tea.
The monasteries for the most part teach in Tibetan but also teach the Mandrian Chinese spoken throughout Han China. In public schools, there are schools in major cities, mandrian is taught. Tibetans are angry about this, part of losing their cultural identity- it is true. I feel for them, but it works the other way too. In America now, some classes are taught in Spanish because the students refuse to learn English. I think governments have the right to have national language.
