the poem tries to explain between freedom and bondage????explain

In this poem the poet has shown a stark contrast in the living style of a tiger in a zoo and a tiger in a forest and between freedom and bondage. A tiger, when kept in a cage, is not happy. He stalks the cage in a rage because he is furious to be held a captive.  In a forest a tiger usually hides in the tall grass and waits for his prey and then pounces on it, but if kept in a cage, he has to eat the food that is given to him. This shows the difference between freedom and bondage.
