The Memoirs of Jahāngīr (Jahāngīrnāma) 2.3

2.3

An inspiration from the hidden world brought it into my mind that, inasmuch as the business of kings is the controlling of the world, I should give myself the name of Jahangir (World-seizer) and make my title of honour (laqab) Nuru-d-din, inasmuch as my sitting on the throne coincided with the rising and shining on the earth of the great light (the Sun). I had also heard, in the days when I was a prince, from Indian sages, that after the expiration of the reign and life of King Jalalu-d-din Akbar one named Nuru-d-din would be administrator of the affairs of the State. Therefore I gave myself the name and appellation of Nuru-d-din Jahangir Padshah. As this great event took place in Agra, it is necessary that some account of that city should be given.
