Lord Buddha offered several pieces of wisdom about life and human nature: We should be thankful for what we have instead of envying others. An insincere friend can damage one more than a wild beast. Anger and resentment will continue unless we let go of those thoughts. We should concentrate on the present moment instead of dwelling on the past or dreaming of the future. Holding onto anger only hurts oneself. We must train our mind to achieve our goals instead of letting the mind control us.
