They have a monastic shared computer or layfolks donate them. I have donated older equipment before, so they can communicate with people like me who do not have the fortune to be able to participate with the Sangha in another way. It is incredibly helpful, and is more valuable to the world. I think while simplicity is important, monks are meant to live in a synergy with laypeople by helping us practice and do Dana. They are here for the benefit of all of us, so I am grateful. Why? Do you think Monks are meant to isolate themselves from the world rather than confronting it with far more directness than laypeople?
