The poem above shows freedom as something natural that exists in our world as a force of nature. However, like the forces of nature, freedom can have devastating and violent effects capable of suppressing those who oppose its objectives and purposes.
When freedom shows its strength and its fury, those who need it tend to be frightened and reject its performance. However, when freedom withdraws and its dominance and violence diminishes, the world goes into chaos and threatens its very existence, causing those who have rejected freedom to call for their action again.
Therefore, the poem shows how freedom is powerful, strong, influential and can have violent and devastating effects, but it is necessary and impossible to live without it.
