《礼记·大学·诚意》英译

所谓诚其意者，毋自欺也。如恶恶臭，如好好色，此之谓自谦。故君子必慎其独也。小人仙居为不善，无所不至，见君子而后厌然，掩其不善而著其善。人之视己，如见其肝肺然，则何异矣。此谓诚于中，形于外，故君子必慎其独也。

曾子曰：“十目所视，十手所指，其严乎！”

富润屋，德润身。心广体胖，故君子必诚其意。

Making Thoughts Sincere

What is meant by “making the thoughts sincere,” is the allowing no self-deception, as when we hate a bad smell, and as when we love what is beautiful. This is called self-enjoyment. Therefore, the superior man must be watchful over himself when he is alone.

There is no evil to which the mean man, dwelling retired, will not proceed, but when he sees a superior man, he instantly tries to disguise himself, concealing his evil, and displaying what is good. The other beholds him, as if he saw his heart and reins; -- of what use is his disguise? This is an instance of the saying – “What truly is within will be manifested without.” Therefore, the superior man must be watchful over himself when he is alone.

The disciple Zeng said: “What ten eyes behold, what ten hands point to, is to be regarded with reverence!”

Riches adorn a house, and virtue adorns the person. The mind is expanded, and the body is at ease. Therefore, the superior man must make his thoughts sincere.
