The Silmarillion

Now all is said concerning the manner of the Earth and its rulers in the beginning of days, and ere the world became such as the Children of Iluvatar have known it. For Elves and Men are the Children of Iluvatar; and since they understood not fully that theme by which the Children entered into the Music, none of the Ainur dared to add anything to their fashion. For which reason the Valar are to these kindreds rather their elders and their chieftains than their masters; and if ever in their dealings with Elves and Men the Ainur have endeavoured to force them when they would not be guided, seldom has this turned to good, howsoever good the intent. The dealings of the Ainur have indeed been mostly with the Elves, for Iluvatar made them more like in nature to the Ainur, though less in might and stature; whereas to Men he gave strange gifts.

For it is said that after the departure of the Valar there was silence, and for an age Iluvatar sat alone in thought.

Then he spoke and said: 'Behold I love the Earth, which shall be a mansion for the Quendi and the Atani! But the Quendi shall be the fairest of all earthly creatures, and they shall have and shall conceive and bring forth more beauty than all my Children; and they shall have the greater bliss in this world. But to the Atani I will give a new gift.'

Therefore to willed that the hearts of Men should seek beyond the world and should find no rest therein; but they  should have a virtue to shape their life, amid the powers and chances of the world, beyond the Music of the Ainur, which is as fate to all things else; and of their operation everything should be, in form and deed, completed, and the world fulfilled unto the last and smallest.

But Iluvatar knew that Men, being set amid the turmoils of the powers of the world, would stray often, and would not use their gifts in harmony; and he said: ''These too in their time shall find that all that they do redounds at the end only to the glory of my work.' Yet the Elves believe that Men are often a grief to Manwe, who knows most of the mind of Iluvatar; for it seems to the Elves that Men resemble Melkor most of all the Ainur, although he has ever feared and hated them, even those that served him.

It is one with this gift of freedom that the children of Men dwell only a short space in the world alive, and are not bound to it, and depart soon whither the Elves know not. Whereas the Elves remain until the end of days, and their love of the Earth and all the world is more single and more poignant therefore, and as the years lengthen ever more sorrowful. For the Elves die not till tile world dies, unless they are slain or waste in grief (and to both these seeming deaths they are subject); neither does age subdue their strength, unless one grow weary of ten thousand centuries; and dying they are gathered to the halls of Mandos in Valinor, whence they may in time return. But the sons of Men die indeed, and leave the world; wherefore they are called the Guests, or the Strangers. Death is their fate, the gift of Iluvatar, which as Time wears even the Powers shall envy. But Melkor has cast his shadow upon it, and confounded it with darkness, and brought forth evil out of good, and fear out of hope. Yet of old the Valar declared to the Elves in Valinor that Men shall join in the Second Music of the Ainur; whereas Iluvatar has hot revealed what he purposes for the Elves after the World's end, and Melkor has not discovered it.

Chapter 2

Of Aule and Yavanna It is told that in their beginning the Dwarves were made by Aule in the darkness of Middle-earth; for so greatly did Aule desire the coming of the Children, to have learners to whom he could teach his lore and his crafts, that he was unwilling to await the fulfilment of the designs of Iluvatar. And Aule made the Dwarves even as they still are, because the forms of the Children who were to come were unclear to his mind, and because the power of Melkor was yet over the Earth; and he wished therefore that they should be strong and unyielding. But fearing that the other Valar might blame his work, he wrought in secret: and he made first the Seven Fathers of the Dwarves in a hall under the mountains in Middle-earth.

Now Iluvatar knew what was done, and in the very hour that Aule's work was complete, and he was pleased, and began to instruct the Dwarves in the speech that he had devised for them, Iluvatar spoke to him; and Aule heard his voice and was silent. And the voice of Iluvatar said to him: 'Why hast thou done this? Why dost thou attempt a thing which thou knowest is beyond thy power and thy authority? For thou hast from me as a gift thy own bring only, and no more; and therefore the creatures of thy hand and mind can live only by that being, moving when thou thinkest to move them, and if thy thought be elsewhere, standing idle. Is that thy desire?'

Then Aule answered: 'I did not desire such lordship. I desired things other than I am, to love and to teach them, so that they too might perceive the beauty of Ea, which thou hast caused to be. For it seemed to me that there is great room in Arda for many things that might rejoice in it, yet it is for the most part empty still, and dumb. And in my impatience I have fallen into folly. Yet the making of thing is in my heart from my own making by thee; and the child of little understanding that makes a play of the deeds of his father may do so without thought of mockery, but because he is the son of his father. But what shall I do now, so that thou be not angry with me for ever? As a child to his father, I offer to thee these things, the work of the hands which thou hast made. Do with them what thou wilt. But should I not rather destroy the work of my presumption?'

Then Aule took up a great hammer to smite the Dwarves; and he wept. But Iluvatar had compassion upon Aule and his desire, because of his humility; and the Dwarves shrank from the hammer and wore afraid, and they bowed down their heads and begged for mercy. And the voice of Iluvatar said to Aule: 'Thy offer I accepted even as it was made. Dost thou not see that these things have now a life of their own, and speak with their own voices? Else they would not have flinched from thy blow, nor from any command of thy will.' Then Aule cast down his hammer and was glad, and he gave thanks to Iluvatar, saying: 'May Eru bless my work and amend it!'

But Iluvatar spoke again and said: 'Even as I gave being to the thoughts of the Ainur at the beginning of the World, so now I have taken up thy desire and given to it a place therein; but in no other way will I amend thy handiwork, and as thou hast made it, so shall it be. But I will not suffer this: that these should come before the Firstborn of my design, nor that thy impatience should be rewarded. They shall sleep now in the darkness under stone, and shall not come forth until the Firstborn have awakened upon Earth; and until that time thou and they shall wait, though long it seem. But when the time comes I will awaken them, and they shall be to thee as children; and often strife shall arise between thine and mine, the children of my adoption and the children of my choice.'
