The soul unattached to sensual gratification is liberated, having no idea of objects of the senses. Liberation, whether with or without the body, produces unselfishness. Know, O son of Raghu that everything in this world is obtainable by our efforts being properly employed. This knowledge — that there is no other way to gain results except but by our efforts — rises like the moon in the human mind and sheds its cooling and delightful influence to the heart. An effort, when directed according to the counsel and conduct of the good in the exercise of the action of the body and mind, is attended with success. Otherwise it is as vain as the freak of a madman.
