Contrast the experience with something worse and you cannot help feeling happy and grateful because... The change from trouble to comfort gives us more pleasure than uninterrupted comfort does.
MaimonidesThe whole object of the Prophets and the Sages was to declare that a limit is set to human reason where it must halt.
MaimonidesWe each decide whether to make ourselves learned or ignorant, compassionate or cruel, generous or miserly. No one forces us. No one decides for us, no one drags us along one path or the other. We are responsible for what we are.
