Galaganatha is like a big toy that people used to play with a long time ago in a place called India. It was a big building that people would go inside and there were cool things inside it like pretty decorations and special pictures. People would go there to do special things like talk to their gods and make wishes. It was a really important place for people to go because it made them feel good inside and it helped them remember their beliefs. Today, there are still some galaganatha buildings that people go to, but not as many as before.
