Ta'wil for Sufism, or Shi'ism, does not possess the same meaning as it does in Mu'tazilite theology and in jurisprudence. It has nothing to do with the debate between the Ash'arites and Mu'tazilites over the literal meaning of the Quran versus rational interpretation of it. Ta'wil in the sense used by the Sufis and Shi'ite sages is the penetration into the symbolic—and not allegorical—meaning of the text which is not a human interpretation but reaching a divinely pre-disposed sense placed within the Sacred Text through which man himself becomes transformed.
