Be thoughtful, even if you are not thinking about the country's righteousness, at least not about your own interests. Sit still and think nothing. Without goals, there will be no progress. But if you have a purpose, what do you want, your heart is impure, easy to attract evil spirits, and easy to get possessed. Therefore, you should cultivate your own righteousness and want something, but not for yourself, for the people and things you care about. Only in this way can we straighten our hearts. It is not recommended that you sit still until you have a good breathing method and a correct sitting method. I like to sit still, too, but I have never done this and no one has taught me.
