§ Of Aulë and Yavanna The Silmarillion

Then Manwë sat silent, and the thought of Yavanna that she had put into his heart grew and unfolded; and it was beheld by Ilúvatar. Then it seemed to Manwë that the Song rose once more about him, and he heeded now many things therein that though he had heard them he had not heeded before. And at last the Vision was renewed, but it was not now remote, for he was himself within it, and yet he saw that all was upheld by the hand of Ilúvatar; and the hand entered in, and from it came forth many wonders that had until then been hidden from him in the hearts of the Ainur.
