Hello little one! Candrakirti was a very smart person who lived a long, long time ago in a place called India. He was really good at thinking about and understanding something called Buddhism, which is a way of living your life that many people in India believed in back then.
Candrakirti wrote lots of important books and talked about some really big ideas. One of the things he explored was something called the "middle way." This means that instead of doing things to the extreme, like eating too much candy or not eating any candy at all, we should try to find a balance in everything we do.
Candrakirti also talked about something called emptiness. This doesn't mean that things are literally empty, but rather that everything is connected and we need to understand how everything is related to really understand the world around us.
So, in short, Candrakirti was a really smart person who talked about middle way and emptiness in Buddhism.
