Highest peak of the music

I've heard much music. Many pieces makes me impressed. But there's one work which can't be forgotten. It is sitting deeply in soul. It seems to be only combination of few hundred sounds. Actually this music is the voice from heart.
Composed over 200 years ago.
Hector Berlioz, famous French composer, admired:

'Is one of those poems that human language does not know how to qualify.'

I agree, there's no word to express second movement in The Piano Sonata No. 14 by Ludwig van Beethoven.



I don't know anything better than that. Maybe you know?
