Never allow sleep to close your eyelids, after you went to bed,The Golden Verses of Pythagoras
Until you have examined all your actions of the day by your reason.
In what have I done wrong? What have I done? What have I omitted that I ought to have done?
If in this examination you find that you have done wrong, reprove yourself severely for it;
And if you have done any good, rejoice.
Practise thoroughly all these things; meditate on them well; you ought to love them with all your heart.
It is those that will put you in the way of divine virtue.
