Description of heaven and hell?

In the following quote from Nicolas of Cusa's writtings offered by Balthasar we see one possibility of what the states of heaven and hell might be like. According to Nicolas we are in a constant state of longing, a longing to know the essence of our being. He goes on to say:
"This indestructable streching-forth is either fulfilled by God, and then is eternal blessedness, in which the spirit is ever moved in a most blessed longing, so that it may attain that of whose gracious closeness it never has enough; or it is, if God does not fulfill it, eternal torture: to possess a rational nature and never to attain to reason."
