Okay, so you know how some people believe in different things like God or multiple gods, right? Well, there are some people in a really big country called Russia who believe in a religion called Buddhism.
Buddhism is when people try to understand their thoughts and feelings and become more peaceful and happy. It was started a long time ago by a guy named Buddha who wanted to help people be less sad.
In the Russian Federation, there are actually different types of Buddhism, but they all share some of the same ideas. Some people who follow Buddhism in Russia think it's important to be kind to all living things and not hurt them. They also like to meditate, which means sitting quietly and focusing on their breathing or on special words.
Buddhism became more popular in Russia after the Soviet Union ended in 1991. Before that, religion was not allowed in the Soviet Union. Now, there are thousands of Buddhist temples and centers all around Russia. Some famous ones are in the Republic of Kalmykia, which is a part of Russia where many people practice Buddhism.
So, that's basically what Buddhism in the Russian Federation is. It's a type of religion that helps people be more peaceful and happy by understanding their thoughts and feelings and being kind to all living things.
