Through the use of his spiritual powers man “must take flight from the cage of the body and become pure spirit…”

To another He said:

Man must take flight from the cage of the body and become pure spirit, for the body is a cage which causes difficulties for man and makes him the captive of nature and involves him in all types of misfortunes. But when a person discards all his physical habits, he is freed from all fetters. As physical powers attract the world of nature, so spiritual powers must break these chains. This condition is not realized by thought alone. The powers of nature are ever alert to allure man. The eye is fascinated by beautiful scenery; the ear is entranced by music; the heart is attracted by delights and human passions. A man may be rich but still he wants more because he is attracted by the world of nature; he has means of livelihood yet he desires more. Therefore, the spiritual powers must dominate so that he may be freed from these fetters and attain salvation. Man is like a bird in a cage. A bird cannot attain freedom merely by knowing that in the free world there are pure breezes, spacious skies, beautiful gardens, pleasant parks and fountains; rather, the bird must find a power to break the cage and soar into the wide firmament.

He then narrated a story about detachment:

The Persian friends travel mostly on foot. They sleep whenever they get tired. They rest wherever they see a shady tree. Once a person came to an Amir. The Amir wished to present him with a gift and with insistence gave him a robe. Later, when he became tired, he lay down under a tree in the forest with the robe folded under his head. But he could not sleep as he repeatedly imagined that a thief was crouching nearby to take away the robe.

At last he rose, threw the robe away and said, ‘As long as this robe is with me, I shall not find rest. To find rest I must give it up.’ How long will you desire a robe for your body? Release your body that you may have no need for a robe.
