Clara presents the God of Akhaten with the 'most important lea in human history'.
The following are the lyrics of the song, 'Wake Up', as shown in 'The Rings of Akhaten', courtesy of link :

"Rest now…..my warrior.
Rest now, hardship is over.
Live. Wake up. Wake up.
And let the cloak, of life – cling to your bones. Cling to your bones.
Wake up, wake up.
Live. Wake up. Wake up.
And let the cloak, of life – cling to your bones. Cling to your bones
Wake up. Wake up!
Live! Wake up! Wake up!
And let the cloak! Of life! Cling to your bones! Cling to your bones!
Wake up! Wake up!
Wake up! Wake up!"

I sincerely hope this artículos corroborates itself to be of any benevolence, to anyone. :D Xxxx

Kind regards, no1drwofan. :D Xxx

The Doctor reminisces about his past.
The Doctor sacrifices all his memories, so as to save Akhaten.
Merry makes bold so as to sing 'Wake Up', as though to calm the God of Akhaten.
