The person whose heart is not sensitive is without feeling; his heart is not living, it is dead. In that case the Divine Spirit is buried in his heart. A person who is always concerned with his own feelings is so absorbed in himself that he has no time to think of another. His whole attention is taken up with his own feelings. He pities himself: he worries about his own pain, and is never open to sympathize with others. He who takes notice of the feeling of another person with whom he comes in contact, practices the first essential moral of Sufism.
