Okay, so you know how sometimes people like to get together with other people who share their beliefs and ideas? They do this so they can help each other and learn from each other. Well, this is kind of like what the Sangha Supreme Council is.
The Sangha Supreme Council is a group of important people in Buddhism who come together to help make decisions for all of the Buddhist monks and nuns. This council is made up of high-ranking monks who have a lot of experience and knowledge about Buddhism.
One of the things the Sangha Supreme Council does is make sure that everyone who wants to become a Buddhist monk or nun is ready and prepared for that life. They also make sure that all the monks and nuns follow the rules and teachings of Buddhism so they can live peaceful and happy lives.
The Sangha Supreme Council is like a big team of wise advisors who want to help everyone in their community live good lives.
