"People are bereft of gratitude, which is not right. One should be grateful for the help they have received from others as long as one is alive. There are two things you must forget: the help you have rendered to others and the harm others have done to you. If you remember the help you have rendered, you will always expect something in return. Remembrance of the harm done to you by others generates in you a sense of revenge. You should remember only the help you received from others.
