Gelug is a type of Buddhism that comes from a country called Tibet. It's like a special way of thinking and living that helps people be good and happy.
Imagine you have a toy that you love playing with, but it doesn't always work the way you want it to. Gelug is like trying to figure out how the toy works and how you can make it work better.
In gelug, people study books that tell them how to be good and kind to others. They also do things like meditate, which is like sitting quietly and thinking about peaceful things. This helps them be kind to themselves and others.
Gelug is like a big family, where everyone tries to help each other be happy and good. They believe that everyone can be happy and good if they work together and try their best.
So, gelug is a special way of living that helps people be good and happy by learning from books, meditating, and being kind to others.
