It passes through the mountains and the desert so easily, that for the royal household, the act of cage-making is a disgrace.

This powerful couplet speaks to the conflict between freedom and societal expectation. The poet states that he can easily survive in the harsh wilderness—the mountains and deserts. However, he finds the simple act of domestic life (settling down, or 'nesting') to be a humiliation or a disgrace for someone who belongs to a royal lineage. It is a declaration of ultimate independence and the refusal to compromise dignity for comfort.
