Others are more acutely aware of their separation from the Source, and long to hasten their approach to the Divine. Tasawwuf addresses their need. This intensification is not incumbent upon believers, but rather an opportunity available to those who pursue it. Islam reveals that Sufism is not something outside of itself, but something contained within itself. When sincere spiritual yearning and practice are combined, the depth and breadth of Islam are revealed.
Inner restlessness becomes profound fulfillment.
Unfortunately, it has not. Instead, we find so-called Sufis who disassociate themselves from Islam, and we find Muslims who have no understanding of Sufism and who, in their ignorance, judge it to be antithetical to Islam. As societies have become fragmented, these links have been broken. We have started to compartmentalize our lives. When a chain is intact, lifting any one link lifts the whole chain.
