Okay kiddo, so a siladhara is a special kind of Buddhist nun. In Buddhism, people try to follow certain teachings and live in a certain way to become more peaceful and happy. Nuns are women who follow these teachings and live in a certain way, just like monks.
Siladhara nuns are part of a special group of nuns who live in a certain place called a monastery, where they all follow the same rules and do the same things. They wear a special kind of clothing, which often includes a brown robe and a shawl-like thing called a kathina.
These nuns spend a lot of time meditating and practicing mindfulness. They also do things to help others, like teaching people about Buddhism and even helping out in the community. They live a very simple life and don't have a lot of fancy things or possessions.
So, in short, a siladhara is a Buddhist nun who lives in a monastery and follows certain teachings and rules to try to become more peaceful and happy. They wear special clothes, practice mindfulness and meditation, and help others.
