You have to examine why you're angry..usually because someone is exhibiting "such and such" a trait. So you take said trait, acknowledge that you too also act that way at times (helps to think of specific examples), and when you accept that, it's balanced by way of understanding. Your impatience for example (being stirred by someone's impatience) then can only become patience. You'll find that the situation can then be viewed with love, rather than anger.
So just by accepting the trait in yourself you have balanced it? Why is their the purpose focusing on the opposite trait?
