Sufism

The ego (nafs) is the greatest veil between the servant and God

Al-Ghazali singles out bodily appetite in particular, hunger and desire, as the most constant and most practicable point of entry for dismantling the deeper self-centeredness that quietly competes with every act of worship.

Book 22 of the Ihya, "Breaking the Two Desires," deals chiefly with the desires of the stomach and the sexual organ, and opens al-Ghazali's larger case that the nafs functions as a veil standing directly between the worshiper and God, not one flaw among many competing flaws but the root system that feeds the others. He treats appetite as the most persistent and most trainable expression of this deeper ego-centeredness, arguing that mastering it is not asceticism for its own sake but a strategic entry point, since these desires are constant and physical and therefore practicable to work on daily, unlike subtler faults such as pride which are harder to catch in the act. His underlying claim is structural: as long as the self orbits its own gratification, every act of worship gets performed alongside a competing, self-interested motive, and it is that competing motive, not any single sin, that constitutes the veil.

• What Sufism says about humility and the ego

  Al-Ghazali treats the nafs not as one fault among many but as the root that feeds the others. He starts with appetite, hunger and desire, because those are the parts a person can actually get hold of.

• What Sufism says about wanting to be admired

  Ghazali's Book 22 argues the nafs is not one flaw among many but the root system feeding the others. He works on appetite first not because hunger matters most, but because it is constant, physical and therefore practicable daily, unlike pride, which is hard to catch in the act.
