There is a universal rule, found in the various sacred books of world religions, which is unique because of its presence in all cultures: "Do to others what you want them to do to you and do not do to others what you would not want done to you"
It's so precious that it is called the "Golden Rule"!
It is expressed in different ways in the sacred books of the major religions and in sapiential literature of many cultures
