“You are wise and powerful. Will you not take the Ring?”

“No!” cried Gandalf, springing to his feet. “With that power I should have power too great and terrible. And over me the Ring would gain a power still greater and more deadly.” His eyes flashed and his face was lit as by a fire within. “Do not tempt me! For I do not wish to become like the Dark Lord himself. Yet the way of the Ring to my heart is by pity, pity for weakness and the desire of strength to do good. Do not tempt me! I dare not take it, not even to keep it safe, unused. The wish to wield it would be too great for my strength. I shall have such need of it. Great perils lie before me.”
