It is entitled "The Seven Story Mountain."
Some quotes:
“Souls are like athletes, that need opponents worthy of them, if they are to be tried and extended and pushed to the full use of their powers, and rewarded according to their capacity.”
“It is only the infinite mercy and love of God that has prevented us from tearing ourselves to pieces and destroying His entire creation long ago. People seem to think that it is in some way a proof that no merciful God exists, if we have so many wars. On the contrary, consider how in spite of centuries of sin and greed and lust and cruelty and hatred and avarice and oppression and injustice, spawned and bred by the free wills of men, the human race can still recover, each time, and can still produce man and women who overcome evil with good, hatred with love, greed with charity, lust and cruelty with sanctity. How could all this be possible without the merciful love of God, pouring out His grace upon us? Can there be any doubt where wars come from and where peace comes from, when the children of this world, excluding God from their peace conferences, only manage to bring about greater and greater wars the more they talk about peace?"
“The soul of man, left to its own natural level, is a potentially lucid crystal left in darkness. It is perfect in its own nature, but it lacks something that it can only receive from outside and above itself. But when the light shines in it, it becomes in a manner transformed into light and seems to lose its nature in the splendor of a higher nature, the nature of the light that is in it.”
