The so-called sincere people in the original text do not deceive themselves, such as bad smell and lust, which is called self-modesty. Therefore, a gentleman must be cautious and independent.

The so-called sincerity of the soul means not deceiving yourself, just like hating that filthy thing and liking beautiful women. This is called self-satisfaction. So a gentleman must be careful when he is alone.

This chapter is a sincere lecture. No, it's forbidden. Self-deception is self-deception and refusal to be honest. Modesty is pronounced as Nuo, and it is quick in the heart. Independence is a place where you can know yourself. Ceng Zi said: "The so-called sincere person in scripture means that when caution is aroused, it really forbids self-bullying, making it as evil as the stench of evil, and truly hating him, but where the evil is, it is necessary to determine. Kindness is like lewdness. You really love him, but you must win wherever it is good. This is the true nature of good and evil. If you don't owe anything, you will get a quick satisfaction in your heart, so it is called self-pity. However, people don't know whether self-deception means true or false. I also know in my heart that although this place is hidden, it is divided into good and evil, and there is no way. Therefore, gentlemen should be extremely cautious here. If they think this is self-deception, they will be banned. If they think it is self-deception, they will be trained and dare not have it. The so-called sincerity in scripture covers this point.
