Si, en inglés la equivalente se llama "the Golden Rule," la regla de oro. La forma estándar, más común, y más familiar es "Do unto others as you would have others do unto you." Creo que este sea un equivalente apropiado por su frase. Este es una variación de un versículo de la Nueva Testamenta, Mateo 7:12. En el inglés anticuado de una traducción tradicional y querida, la "King James version,"' "Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets." En una traducción moderna, “In everything, treat others as you would want them to treat you, for this fulfills the law and the prophets.“ En la traducción en español, Nueva Version Internacional (NVI), “Así que en todo traten ustedes a los demás tal y como quieren que ellos los traten a ustedes. De hecho, esto es la ley y los profetas.”

"Treat others how you want to be treated" (informal) or "Do unto others as you would have others do unto you." (more formally)

"Treat others as you yourself want to be treated". "Do unto others as you yourself would want to be done to you", etc. You can find online parallel Bibles with English/Spanish and you can read how they are translated. The more you read in English, with Spanish on the same page, the more you will learn.

In English it means, "Treat the least among us as you yourself would want to be treated."

It means, "treat the least among us the way that you yourself would want to be treated."
