The concept of al-Atwar al-Seb'a (seven stages) is an important issue in the Khalwati tradition. Khalwati Sufis evaluates the seven stages of human ego within the spiritual experience they have experienced and have revealed the application of which measures used in self-development phases with different criteria. For this reason, a rich culture of al-Atwar al-Seb'a has been formed in the Khalwati tradition and many pamphlets have been written on this topic. It is important for today's academic world to deal with these issues within the framework of spiritual psychology. Because a new spiritual psychology tradition has begun to emerge as parallel to modern psychology. By force of the method of modern psychology its perception of self-development is more physio-psychological and this viewpoint neglects the inner/spiritual dimension of man. On the other hand, the self-development model of the Sufi tradition by force of the Islamic belief is psycho-spiritual and accordingly the spiritual development of the human ego exists. In this paper, we will reveal Jamal Khalwati's thoughts about human ego and its spiritual development in seven stages, and try to show the contribution of them to the development of Sufi psychology.
