A sentence from Edward Luce's In Spite of the Gods:
Aurangzeb's great grandfather, Akbar, tried to fuse Islam, Hinduism and other religions into a new religion, which he called Din Ilahi, but without much success.
More on it here:
Like Islam, it was rationalistic and was based on one overriding doctrine, the doctrine of tawhid : God is one thing and is singular and unified. Akbar also elevated the notion of wahdat-al wujud , or "unity of the real," to a central religious idea in his new religion. The world, as a creation of God, is a single and unified place that reflects the singularity and unity of its creator. Finally, Akbar fully subscribed to the Islamic idea of the Perfect Man represented by the life of the Prophet or by the Shi'ite Imamate. There is little question that Akbar accepted Abu'l Fazl's notion that he was the Divine Light and was a Perfect Man. He assumed the title, "Revealer of the Internal and Depictor of the Real," which defined his role as a disseminator of secret knowledge of God and his function of fashioning the world in the light of this knowledge.Posted by Ideofact at April 23, 2007 11:12 PM
In addition to Islam, however, the Din-i Ilahi also contained aspects of Jainism, Zoroastrianism, and Hinduism. The Din-i Ilahi borrowed from Jainism a respect and care for all living things, and it derived from Zoroastrianism sun-worship and, especially, the idea of divine kingship. This latter innovation deeply disturbed the ulama ; they regarded it as outright heresy. The notion of divine kingship, however, would last throughout the history of the Mughal Empire.
