Okay, so you know about Buddhism, right? Well, in China, some people practice a kind of Buddhism that's a little bit different. It's called "esoteric" because it has some secret or hidden practices.
Picture this: Imagine you're in a big castle and there's a big secret room that nobody knows about. Only a few special people know how to get in there. That's kind of how esoteric Buddhism works.
One of the things that makes esoteric Buddhism different is that it uses special hand movements that are called "mudras". It's almost like doing a dance with your hands! Each mudra is connected to a different teaching or idea in Buddhism.
Esoteric Buddhists also use special words and sounds called "mantras". They're like magic words that are supposed to have power. Buddhists believe that saying these mantras can help calm your mind and bring you closer to enlightenment.
Another thing you might see in esoteric Buddhism is images of special gods and goddesses. These gods and goddesses have different meanings and are supposed to help people understand different ideas and teachings in Buddhism.
So that's just a little bit about Chinese esoteric Buddhism. It's kind of like a secret club within Buddhism, with special hand movements, magic words, and special images that help people understand and connect with the teachings of Buddhism.
