Tengri is mentioned many times in "the Secret History of the Mongols", written in 1240. The book starts by listing the ancestors of Genghis Khan starting from Borte Chino (Blue Wolf) born with "destiny from Tengri". Bodonchar Munkhag the 9th generation ancestor of Genghis Khan is called a "son of Tengri". When Temujin was brought to the Qongirat tribe at 9 years old to choose a wife, Dei Setsen of the Qongirat tells Yesugei the father of Temujin (Genghis Khan) that he dreamt of a white falcon, grasping the sun and the moon, come and sit on his hands. He identifies the sun and the moon with Yesugei and Temujin. Temujin then encounters Tengri in the mountains at the age of 12. The Taichiud had come for him when he was living with his siblings and mother in the wilderness, subsisting on roots, wild fruits, sparrows and fish. He was hiding in the thick forest of Terguun Heights. After three days hiding he decided to leave and was leading his horse on foot when he looked back and noticed his saddle had fallen. Temujin says "I can understand the belly strap can come loose, but how can the breast strap also come loose? Is Tengri persuading me?" He waited three more nights and decided to go out again but a tent-sized rock had blocked the way out. Again he said "Is Tengri persuading me?", returned and waited three more nights. Finally he lost patience after 9 days of hunger and went around the rock, cutting down the wood on the other side with his arrow-whittling knife, but as he came out the Taichiud were waiting for him there and promptly captured him. Toghrul later credits the defeat of the Merkits with Jamukha and Temujin to the "mercy of mighty Tengri" (paragraph 113).
