Rule of Saint Benedict

Okay kiddo, do you know that some people like to live a special way of life by following certain rules? Yes? Good! So, the Rule of Saint Benedict is a set of rules that a monk named Benedict created a long time ago for people who wanted to live like him.
These rules involved things like waking up early, being kind to others, and praying often. See, the goal was to live a holy and happy life while doing work that benefited the community.
The important thing to remember is that these rules were made to help people live a good life, just like how your grown-up might make rules to help you stay safe or be a good person.
