“The Sufi path is marked by a number of different stages or stations (maqdm/maqdmdt) which the Sufi traveller (sdlik) passes through as he advances on the path. On his way the Sufi also experiences various psychological and emotional states (hdl/ahwdf). [...] The Sufi’s progress along the path is hindered by the machinations of the self (nafs), that is, the ego-self or what is called in the Qur’an the self that incites or exhorts to evil {al-tiafs al-ammdrah bi-al-su). In order to maintain his progress along the path to God the Sufi must be able to control the ego-self by disciplining it, and by continually blaming and abasing it.”
