What is the climax of Shelley's poem "To a Skylark"?

We look forward and backward, worrying about

things that do not exist.

Our most sincere smiles,

are also intertwined with a certain kind of Anguish,

Our most beautiful music is the tune that best expresses grief.

However, even if we can abandon

hatred, arrogance and fear,

even if we are born unable

to shed a tear,< /p>

We don’t know how to get close to your happiness.

I really like Shelley’s poems.

Hope this helps!
