Let us learn to regard the mistakes of human beings as their own affair and the accomplishments of human beings as something that concerns all of humankind. People’s errors belong to their karma; their deeds concern humanity. Let us learn not to be troubled by people’s mistakes; they themselves must atone for them. Let us rather be thankful for their accomplishments, for the entire evolution of humanity lives from them.
