In his text, Hujwiri describes the “veils which should be lifted” in order to purify one's heart and really pursue Sufism. Hujwiri argues for the importance of “morals” over “formal practice” in Sufism.[9] He was the first to directly address the problematic diversity in Muslim belief during his time. In Kashf ul Mahjoob, he describes various Sufi approaches to theoretical ideas, linking them to particular key Sufi figures.[10]
