Furthermore, the tendency to doubt, the tendency to distress, the tendency to fear, suspicion, and confusion, where does it all come from? It all comes from the thought of getting something in return, anxiety as to whether anyone will give one back what one has given him. That is the thought behind it. And as to doubt, what is doubt? Doubt which gathers round the soul is like a cloud passing before the sun, keeping its light from shining out. But the unselfish one has good reason for his trust; he looks through the clouds and says, 'What do I care if I am not rewarded, I don't mind. I know what to do: give service; that is all the satisfaction I want. I do not look for anything in return. This is where my duty ends.' He is blessed because he has conquered; he has won his battle.
