Humility.

There is a peace that comes in sadness and humility; in total dejection. It is a peace that comes from a cessation of striving, of justifying your actions, of being cheerful when you do not feel so. Nothing more is required now. Only this weight of knowledge that you can taste. In total defeat, humility and sadness become the things that you breathe and taste, and since there is nothing else in you, you move into the sadness like a new home far away from the one you grew up in. And the peace comes from knowing how God has it all together, and you have nothing together. And this no longer inspires the slight affront to your ego that it formerly would have.

A nobility of meekness is a beautiful thing, but to arrive there, you must go by the way of ignobility and humiliation. You must forget about yourself as an individual, as a thinking, rational being, as an entity taking up space. These things will be added later, but at the beginning of the process, you are robbed of the accoutrements of nobility and gentlemanliness. 

And when you've lived for a while in that sadness, with meekness, you soon realize that there is nothing sad about the place where you are. You become aware of the bottom-of-the-well-place where you have lived, and you simply begin to climb up.

The only wisdom we can hope to acquire 

Is the wisdom of humility: humility is endless.

- T.S. Eliot, The Four Quartets
