Always follow these two rules: first, act only on what your reasoning mind proposes for the good of humanity, and second, change your opinion if someone shows you it's wrong. This change of mind must proceed only from the conviction that it's both correct and for the common good, but not because it will give you pleasure and make you popular.
Since you are an integral part of a social system, let every act of yours contribute to the harmonization of social life. Any action that is not related directly or remotely to this social aim disturbs your life, and destroys your unity.
Let your one delight and refreshment be to pass from one service to the community to another, with God ever in mind.
The true joy of humankind is in doing that which is most proper to our nature; and the first property of people is to be kindly affected towards them that are of one kind with ourselves.
