The quote in the background is part of the lyrics to Dream Refrain by SOUND HOLIC (that one Touhou song)
Here are the lyrics-

How little, through the million history,
the dream of human was
Grown and withered, O Spirits
—nothing but of destiny...
The pleasure of maltreating a trampling lamb
was misted by the locked destiny and eternal mystery
Who created with his sympathy
the symphony forbidden by the barrier of the world?
The word of lunatic condemnation for impatience
collided with a kiss
Until the season of scattering,
blossom for the moment, you sons of man
Neither the luminescence of tide rising and ebbing
nor the reincarnation of splendid constellations
would not light up the temporary answer
—nothing but refraining of destiny
How little, through the million history,
the dream of human was
Spirits grow and wither
—nothing but refrain of destiny
A fully blossomed flower gains fruits and drops seeds
A flower lived multicolored could not but return to the soil
Philosophy of being explained death, entrusted the wind
leading to the past, then, and future
