"目标是在内心变得足够强大，以至于没有任何外界因素能在未经你有意识地允许的情况下影响你的内在健康。"

Simplified Meaning:

Think of becoming strong like a big tree. A big tree faces wind, rain, and storms, but it stands firm because its roots go deep and strong. It's not easily knocked over by bad weather. Similarly, people can try to be strong inside, so when things go wrong outside, like a bad day or someone being mean, it doesn’t upset them easily. For example, imagine you study really hard for a test, and you're confident in what you know. Even if the test is tough, you don’t feel as worried because you prepared well. This confidence is like being strong inside. If you try to practice things like staying calm, thinking positively, and understanding your own feelings, you'll get better at not letting outside things mess with your peace. You can apply this in daily life by taking a few moments each day to relax, think positively, or remember good things about yourself. Over time, you will feel more in control and less affected by what happens around you. This way, you give yourself permission to stay peaceful and happy, no matter what’s going on outside.
