该句使用must表达强制性义务语气。
In life, the truth often stings. However, one should not harbor resentment when hearing harsh truths, nor feel frustration when facing adversity. Both harsh words and difficult circumstances can ignite our fighting spirit, using "unpleasant truths" to continuously refine our character. Just as bitter medicine heals, "unpleasant truths" aid in spiritual cultivation. Avoid being superficial—turning away at the first sign of criticism or blaming others for setbacks. Conversely, if one only seeks praise, one may become complacent, lose touch with reality, and lose the drive to improve.
We must constantly reflect on our conscience, using it as a standard to govern our actions. When we act against morality, the first punishment comes from within. Integrity and honesty constitute our conscience and serve as our internal judge. The guilt of a compromised conscience is one of life's greatest pains, leading to sleepless nights. To live a life of peace, one must remain upright and sincere. When honesty shines upon the soul, shadows vanish. Every person has an internal scale; every transgression is weighed by the heart, regardless of whether others know.
Humans can be paradoxical: often ignoring righteous advice while readily accepting empty flattery.
生活中，真相往往最伤人。然而，听到逆耳之言时，切不可心生怨愤；身处逆境时，也不必满腹牢骚。因为逆耳的真言与艰难的处境，足以激发我们的斗志，以“不美之信言”不断洗礼自我。良药苦口能治病，“信言不美”亦能利于修行。切忌像某些肤浅之辈那样，一听忠言就拂袖而去，一遇不如意就怨天尤人；若一味沉溺于“美言”，被夸奖便得意扬扬，不仅会失去对人生的真实认知，让生活变得放荡，更会在无形中削弱奋发向上的精神。
我们应当时刻反省内心，用良知与道德准则来约束和管理自己。因为违背道义之举，首先会遭受来自内心的审判。正直与诚实是良知的体现，也是内心最严厉的审判官。良心的惩罚是最痛苦的折磨，是人生苦难的根源之一，背负着良心的谴责会让人寝食难安。唯有保持坦荡，让内心充满正直与诚实，才能驱散心头的阴霾。每个人心中都有一杆秤，任何违背道德的事都会在内心留下印记，无论外界是否知晓，道德的底线永远在那里。
人类有时表现得十分矛盾：面对正确的规劝，往往视其为耳旁风；而对于虚假的奉承，却又甘之若饴。
"Whenever I reflect I feel that I may not have been sufficiently filial."
"What is it that binds you and keeps you from moving forward?"
"We look outward too much, but look inward at our souls too little."
"Do not blame others for disappointing you; blame yourself for having too high expectations."
"If you want to know what others say about you behind your back, first examine how you speak of others"
