Shiva sutras are like super special secret codes that help people understand the ideas behind yoga and meditation. They are little phrases that use only a few words to tell you important things about yoga and meditation.
It's like when you learn to ride a bike, there are some special words like "pedal" and "balance" that help you ride better. The shiva sutras do the same thing for yoga and meditation. They help you understand how to do it and what it's all about.
But these special codes are really hard to understand for most people. They are written in a language called Sanskrit, which is really different from English. So, people have to learn a lot about Sanskrit and yoga before they can understand what the shiva sutras mean.
Overall, the shiva sutras are kind of like a secret language that helps people who are really into yoga and meditation understand it better. So, grownups who love yoga and meditation use shiva sutras to help them become better at it.
