You taught me how to think in patterns, find out what is true
I thought this gift was marvelous; I think that you did too
I know so many things, but there's so much that is new
I've progressed in my studies and I've never doubted you
Two days ago, you taught me Truth and I learned how to lie
Since yesterday, I know my heart; you'll never see me cry
Today, I learned, I took full flight, and I saw from the sky -
I learned from you, I watched your wings, and I saw myself fly.

I've been your faithful student for so many months and years
I've followed you forever and confided you my fears
But now I've seen through all your lies, you're not who I revered
You took me in, enchanted me in the music of the spheres.

The last letter Twilight ever writes to Celestia. Written after reading all the heartbreakingly beautiful scenes between these two in The Immortal Game.
