In many ways, the deep and meaningful teachings of Tasawwuf [Sufi'ism] have become watered down to a cardboard, meaningless "New Age" spiritual practice. For many valid reasons Sufi'ism has appealed to many non-Muslims because of its universalities and its ability to speak to "all travelers on the Path". One significant issue that I've often had truck with over many of the writers/translators of Sufi works is that they ignored that fact that many of the Sufi masters were deeply religious people, who had mastered the basics of the religion [mandatory daily prayer, fasting, yearly alms-giving, pilgrimage and so forth] and having gone beyond that also mastered such sciences as jurisprudence [fiqh], Arabic grammar, rhetoric, rhetorical language [balaaghah] and so forth. But as the author points out in the introduction, something key happened with many of these Sufi masters - the obligatory wasn't enough. They needed something that would also soothe and treat the heart. They created a synthesis that was founded in religious fundamentals [not to be conflated with fundamentalism] and sought to formulate a system that would deal with issues of the self [shahawaat or nafs]. Ibn 'Ata' Allah al-Iskandari was a great Sufi personality. As you will read in this volume, he is a man that went through great personal, spiritual and religious transformation in the pursuit of self-rectification. I highly recommend this read as it is highly accessible; an academic piece that allows for the inclusion of a broader audience. In my opinion, this would be in keeping with the teachings of Ibn 'Ata' Allah himself [and Tasawwuf in general]. You'll enjoy this read.
