It approaches the practice using categories of improvised music to establish a framework for analyzation. Its ritualized formal structure, illustrated via selected talks of Shaykh Nazim Adil al-Haqqani, discloses the underlying—and assumingly primary—function to provoke prolonged states of raised awareness in listeners and condition their sympathetic nervous system.

In an extensive discussion based on several years of field research in Cyprus, the book relates this intention to similar practices in other traditional knowledge systems by proposing psychophysical interpretations based on psychology, biochemistry, neuroscience, or quantum physics. It will appeal to scholars and students of Sufism, Islamic studies, and comparative religion, as well as those interested in performance studies and improvised music, interpersonal communication, and education.
