As for sleep, keeping vigil is enough. There are people who are vigilant about some things, and there are people who are vigilant about all things. Not a knowledge that you learn, but a knowledge that you suffer. That is Orthodox spirituality. Rather, seek to take care of what you have so as to sanctify it.
Nothing is cheaper than money.
Better hell here than in the other world. It is not what we do, but what we are. The raso speaks. If you have love for the whole world the whole world is beautiful. Someone said that the Christian is one who purifies love and sanctifies activity.
