In Attar's Elahi-Nameh, the tale of Ahmad Ghazali concerning Jacob and Joseph serves as an allegory for the Sufi concepts of mystical union (visal) and the annihilation of the self (fana). When Jacob finally embraces Joseph in Egypt, he cries out asking where Joseph is, demonstrating that in the state of complete union, the lover is so absorbed in the Beloved that all dualistic distinctions between seeker and sought disappear. Jacob's declaration that he has 'become Joseph entirely' and 'found himself' illustrates the ultimate stage of spiritual realization, where finding the divine Beloved is equivalent to discovering one's true, undivided self.
