“If you work at that which is before you, following right reason seriously, vigorously, calmly, without allowing anything else to distract you, but keeping your divine part pure, as if you should be bound to give it back immediately; if you hold to this, expecting nothing, fearing nothing, but satisfied with your present activity according to nature, and with heroic truth in every word and sound which you speak, you will live happy. And there is no man who is able to prevent this.”
