The Six Perfections
by Dale. S. Wright

This remarkable book informs CxD through and through.

The heart cannot be taught in a classroom intellectually, to students mechanically taking notes. Good wise hearts are obtained through lifetimes of diligent effort to dig deeply within and heal lifetimes of scars. you can't teach it or email it or tweet it. It has to be discovered within the depths of one's own heart when a person is finally ready to go looking for it, and not before.

The Never Ending Quest
by Clare W. Graves

Isn’t it better to try for an idealized version of the world, than not to have tried at all?

there are, strictly speaking, no enlightened people; there is only enlightened activity.    
The characters tend to err the they reject the grubby and complex circumstances of everyday life for abstract and radical notions. They thrive when they work within the rooted spot, the concrete habit, the particular reality of their town and family. Eliot herself believed that the beginning of wisdom was the faithful and attentive study of present reality, a thing itself, a person herself, unfiltered by abstract ideas, mists of feeling, leaps of imagination or religious withdrawals into another realm. 
Montaigne on his penis: "It intrudes so tiresomely when we do not require it and fails us so annoyingly when we need it most."    Montaigne on Character: "Everyone can play his part in the farce, and act an honest role on the stage. But to be disciplined within, in one's own breast, where all is permissible and all is concealed. That is the point." 
"It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking the meaning of life, and instead think of ourselves as thoswe who were being questioned by life––daily and hourly."
