Rumi's great book of wisdom-infused poetry contain myriad lessons on the importance of faith, with the culture and lessons of spiritual, Biblical and Islamic teachings featuring strongly. In authoring his masterwork, Rumi quoted the Qu'ran, the Bible and several spiritual forebears. Wishing to align his poetry in order to tell tales of man and man's place in the world, Rumi drew upon a variety of religious and spiritual sources to create a poetic compendium of supreme profundity and depth. The Masnavi was praised as one of the finest works of mystical literature ever seen. It is in the Masnavi that Persia's place between the spiritual cultures of Asia and the Middle East is evidenced. Rumi himself, while undoubtedly an Islamic scholar of great ability, did not feel confined to the faith; he saw spiritual value in a range of disciplines, and asserted that the light of Mohammed's prophecy does not leave faithful Christians, Jews, Zoroastrians or other denominations behind.
