If we do not protect our own heart from harm, we can be killed at every moment. Amir, the poet, says, "Why did you not kill me before you wounded my heart? It would have been better to kill me first." We must consider what the world is and what it can give. We must give and not expect to take the same as we give. A kick for a kindness, a blow for a mercy is what the world gives. We must not expect the world to be as we are expected to be. If we receive some good, it is well. If becomes a composer; or "I should be a teacher", and becomes a teacher, then he is not hopeless.
