Premanand Maharaj Ji
What is a simple test to know whether an action is right or wrong?
Don't do to others what you dislike
What seems wrong to you should not be done, and the test is not treating others as you would not want to be treated. Bhagwan sits in every heart, so almost everyone knows whether what they are doing is wrong, even if we say we didn't know.
Do not behave toward others in a way you would not like for yourself.
