So, imagine you have a big family with lots of cousins and uncles and aunts. And imagine that some of you have different ideas about how to do things, like what you should eat for dinner or when you should go to bed.
Now, the Congress of the Jewish Religious Organizations and Associations in Russia is kind of like a big family meeting for Jewish people in Russia. They get together to talk about how they want to practice their religion and how they can work together to make sure their traditions are respected and protected.
It's important for this Congress to happen because there are lots of different kinds of Jewish people in Russia and they want to make sure they can all worship and practice their beliefs in the way that feels right to them.
So, just like how your family might have a big meeting to figure out how to make everyone happy, the Congress of the Jewish Religious Organizations and Associations in Russia has a big meeting to figure out how to make sure all Jewish people in Russia can be happy and feel like they belong.
