If thou workest at that which is before thee, following right reason seriously, vigorously, calmly, without allowing anything else to distract thee, but keeping thy divine part pure, as if thou shouldst be bound to give it back immediately; if thou holdest to this, expecting nothing, fearing nothing, but satisfied with thy present activity according to nature, and with heroic truth in every word and sound which thou utterest, thou wilt live happy. And there is no man who is able to prevent this.
As those who try to stand in thy way when thou art proceeding according to right reason, will not be able to turn thee aside from thy proper action, so neither let them drive thee from thy benevolent feelings towards them, but be on thy guard equally in both matters, not only in the matter of steady judgement and action, but also in the matter of gentleness towards those who try to hinder or otherwise trouble thee.
