If thou workest hard at which is before thee, following right reason seriously, vigorously, calmly, and without allowing anything else to distract thee, but keeping thy divine pure, as if thou shouldst be bound to give it back immediately.

当你做摆在你面前的工作时，你要认真地遵循正确的理性，精力充沛，宁静致远，不分心于任何别的事情，保持你神圣的部分纯净，仿佛你必定要直接把它归还似的。
