Mencius - Book 5, Part 1, Chapter 5C

Chang said, 'I presume to ask how it was that Yâo presented Shun to Heaven, and Heaven accepted him; and that he exhibited him to the people, and the people accepted him.' Mencius replied, 'He caused him to preside over the sacrifices, and all the spirits were well pleased with them; thus Heaven accepted him. He caused him to preside over the conduct of affairs, and affairs were well administered, so that the people reposed under him; thus the people accepted him. Heaven gave the throne to him. The people gave it to him. Therefore I said, "The sovereign cannot give the throne to another."
