“Spirit of the midnight dream,
What is now upon thy wing?
Earth sleeps in the moonlight beam;
O'er that sleep what wilt thou fling?”

Context: Now then, Nick, wilt thou not sleep?
Nicholas glanced up from the plaquette on which he had been studying the Pali canon of Buddha’s teachings. He sighed and set it aside...
You don’t look like revelation has struck you, somehow.
No, Spirit.
This ain’t any better than the Tao?
No.
Nor the Bhagavad Gita? Nor the Avesta, neither?
No.
I thought certain you’d like them Gnostic Gospels.
Nicholas shrugged.
And I reckon you ain’t even looked at that nice book on Vodou.
Spirit, this is futility. What do the best of them but recapitulate the Ten Commandments, in one form or another? And I find no proof that men have obeyed strange gods any better than the God of the Israelites, or learned any more of the true nature of the Almighty. Shall I worship a cow? Shall I spin paper prayers on a wheel? I’d as lief go back to eating fish in Lent lest God smite me down, or pray to wooden Mary to take away the toothache.
Well, son, allowing for the foolishness, which I reckon depends on what port you hail from—ain’t there any one seems better than the rest?
None, Spirit. That I must be kind and do no harm, I needed no prophets to tell me; but not one will open his dead mouth to say what kind and harmless Lord would create this dreadful world, said Nicholas...
What do I tell my boy, then, if he gets the shakes about eternal life?
Set up no gods for thine Alec, Spirit. Nicholas lay back and put his arms about Mendoza, pulling her close. There is love, or there is nothing. The rest is vanity.

Let not sleep e'er close thy eyes
Without thou ask thyself: What have I omitted and what done?
Abstain thou if 'tis evil; persevere if good.
As translated by Fabre d'Olivet
Do not let sleep close your tired eyes until you have three times gone over the events of the day. 'What did I do wrong? What did I accomplish? What did I fail to do that I should have done?' Starting from the beginning, go through to the end. Then, reproach yourself for the things you did wrong, and take pleasure in the good things you did.
As quoted in Divine Harmony: The Life and Teachings of Pythagoras by John Strohmeier and Peter Westbrook. (1999)
The Golden Verses
Context: Let not sleep fall upon thy eyes till thou has thrice reviewed the transactions of the past day. Where have I turned aside from rectitude? What have I been doing? What have I left undone, which I ought to have done? Begin thus from the first act, and proceed; and, in conclusion, at the ill which thou hast done, be troubled, and rejoice for the good.
