Then Ilúvatar spoke, and he said: 'Mighty are the Ainur, and mightiest among them is Melkor; but that he may know, and all the Ainur, that I am Ilúvatar, those things that ye have sung, I will show them forth, that ye may see what ye have done. And thou, Melkor, shalt see that no theme may be played that hath not its uttermost source in me, nor can any alter the music in my despite. For he that attempteth this shall prove but mine instrument in the devising of things more wonderful, which he himself hath not imagined.'
Then the Ainur were afraid, and they did not yet comprehend the words that were said to them; and Melkor was filled with shame, of which came secret anger. But Ilúvatar arose in splendour, and he went forth from the fair regions that he had made for the Ainur; and the Ainur followed him.
But when they were come into the Void, Ilúvatar said to them: 'Behold your Music!' And he showed to them a vision, giving to them sight were before was only hearing; and they saw a new world made visible before them, and it was globed amid the Void, and it was sustained therein, but was not of it. And as they looked and wondered this World began to unfold its history, and it seemed to them that it lived and grew. And when the Ainur had gazed for a while and were silent, Ilúvatar said again: 'Behold your Music! This is your minstrelsy; and each of you shall find contained herein, amid the design that I set before you, all those things which it may seem that he himself devised or added. And thou, Melkor, wilt discover all the secret thoughts of thy mind, and wilt perceive that they are but a part of the whole and tributary to its glory.'
