"None of you is a true believer unless he wishes for his brother what he wishes for himself."
"न तत्परस्य संदध्यात्प्रतिकूलं यदात्मनः। एष संक्षेपतो धर्मः कामादन्यः प्रवर्तते ॥"

The Golden Rule is the principle of treating others as one would want to be treated by them. It is sometimes called an ethics of reciprocity, meaning that one should reciprocate to others how one would like them to treat the person. Various expressions of this rule can be found in the tenets of most religions and creeds through the ages.
"None of you is a true believer unless he wishes for his brother what he wishes for himself."
"Whatever I wish for myself, I am to wish for another; and whatever I do not wish for myself or for my friends, I am not to wish for another. This injunction is contained in Gods words: Love your neighbor as yourself."
"Do not that to another, which thou wouldest not have done to thyself."
"What you shun enduring yourself, dont impose on others. You shun slavery - beware of enslaving others!"
"...bonum quod unusquisque qui virtutem sectatur, sibi appetit, reliquis hominibus etiam cupiet."
