A person's soul harms and dishonors itself most when it becomes like a tumor or growth on the world. To be upset and angry about anything that happens is to rebel against the nature of the universe. We are all part of that universe.
A man's soul doth wrong and disrespect itself first and especially, when as much as in itself lies it becomes an aposteme, and as it were an excrescency of the world, for to be grieved and displeased with anything that happens in the world, is direct apostacy from the nature of the universe; part of which, all particular natures of the world, are.
