Any conscientious scholar of the Adi Granth will be struck by the fact that both in its origin and development, in its soul and body, it belongs to a larger literature of a similar nature and ethos found all over India. And the common source of them all is the Upanishads, the Yogas, the Puranas and the Mahabharata. All the spiritual categories, approach, message, motif, images, metaphors and illustrative material derive from that source, and only the language is regional. But nothing is lost in the repetition and the message remains fresh and invigorating; in fact, it acquires a new confirmation as it is renewed in the lives of Godmen from generation and region to region. The Adi Granth reproduces hundreds of passages and phrases almost verbatim from the older scriptures.
