Sufi psychology has influenced many areas of thinking both within and outside of Islam, drawing primarily upon three concepts. Ja'far al-Sadiq (both an imam in the Shia tradition and a respected scholar and link in chains of Sufi transmission in all Islamic sects) held that human beings are dominated by a lower self called the nafs (self, ego, person), a faculty of spiritual intuition called the qalb (heart), and ruh (soul). These interact in various ways, producing the spiritual types of the tyrant (dominated by nafs), the person of faith and moderation (dominated by the spiritual heart), and the person lost in love for God (dominated by the ruh).
