The last verse from a poem called 'We Are Made One with What We Touch and See' by Oscar Wilde.
I'm not really into poetry... Too deep for me. But this bit, I really like :D

We shall be notes in that great Symphony
Whose cadence circles through the rhythmic spheres,
And all the live World's throbbing heart shall be
One with our heart, the stealthy creeping years
Have lost their terrors now, we shall not die,
The Universe itself shall be our Immortality!

... Even though it doesn't rhyme :p
