RevolutionaryGirlUtena/TheChickSpeech

"If it cannot hatch from its shell, the chick will die without ever truly being born.
We are the chick; the world is our egg.
If we don't break the world's shell, we will die without truly being born.
Smash the world's shell!
For the Revolution of the World!"

Apparently, the Japanese is:
"tamago no kara wo yabureneba hinatori wa umarezu ni shin de yuku. warewa ga hina da. tamago wa sekai da. sekai no kara wo yaburaneba warera wa umarezu ni shin de yuku. sekai no kara wo hakai se yo. sekai wo kakumei suru tame ni!"

An oft-repeated speech in RevolutionaryGirlUtena, deeply laden with meaning. Alternatively, an overused metaphor SignifyingNothing. Your choice.

Apparently, it's a reference to a passage in Herman Hesse's Demian. Which is why the name of the piece of background music is "Kami no Na wa Abraxas" - "The God's Name is Abraxas".
