Monasteries, abbeys and priories all have their own churches attached to the living quarters. Monastic churches are often large, ornate and grand buildings. In the UK some abbey churches were so grand that when the monasteries were destroyed by Henry VIII the churches survived, many of which became cathedrals afterwards as they were so grand. The churches were built by the monks themselves as many trained to be excellent masons and builders.

I believe the answer to be monks
Tibetan monks do not traditionally believe in a single all-powerful god like in some monotheistic religions. Instead, they focus on spiritual development, meditation, and compassion towards all beings. Their beliefs are rooted in Buddhist philosophy, which does not center around a creator god.
I am Muslim and in our religion we do believe in ghosts as "Gin" they do exist and we do believe in them. It is in our religion.
