When someone's wrongdoing offends you, look at yourself first. Ask what you are guilty of in the same way. Maybe you also think happiness comes from being rich, living in pleasure, or getting praise. Think about this and your anger will fade. Remember that the person was forced by their own error and ignorance to act this way. How can they choose differently while they still think like that? So if you can, help them see what's driving them to act as they do.
When thou art offended with any man's transgression, presently reflect upon thyself; and consider what thou thyself art guilty of in the same kind. As that thou also perchance dost think it a happiness either to be rich, or to live in pleasure, or to be praised and commended, and so of the rest in particular. For this if thou shalt call to mind, thou shalt soon forget thine anger; especially when at the same time this also shall concur in thy thoughts, that he was constrained by his error and ignorance so to do: for how can he choose as long as he is of that opinion? Do thou therefore if thou canst, take away that from him, that forceth him to do as he doth.
