"For with the consent of
Eru they sent members of their own high order, but clad in bodies as of
Men, real and not feigned, but subject to the fears and pains and weariness of the earth, able to hunger and be slain; though because of their noble
spirits they did not die, and aged only by the cares and labours of many long years. And this the
Valar did, desiring to amend the errrors of old, especially that they had attempted to guard and seclude the Eldar by their own might and glory fully revealed; whereas now their emissaries
were forbidden to reveal themselves in forms of majesty, or to seek and rule the wills of Men or Elves by open display of power, but coming in shapes weak and humble were bidden to advise and persuade Men and Elves to do good, and to seek to unite in love and understanding all those whom
Sauron, should he come again, would endeavour to dominate and corrupt."
