We have returned from the lesser struggle to the greater struggle: the harder fight is inside
Sufis repeat this line of the Prophet whenever outward effort starts to look like the whole job. The mind that keeps generating arguments, defenses and impressive plans is the harder ground. Winning there happens through years of small, unglamorous returns rather than one decisive push.
Kibr: Pride
Al-Ghazali treats this as the swelling that makes a person quietly rank themselves above everyone else. It grows fastest in someone who has learned a lot, since knowledge gives them a platform to stand on. Once being right matters more than being corrected, pride is already doing their thinking for them.
God is veiled by seventy thousand veils of light and darkness: even bright ideas can block the view
Al-Ghazali builds his Niche of Lights on this saying, and the bright veils are the ones people miss. Dark veils are obvious faults; bright ones are a person's own fine thoughts about God, held so tightly that nothing new gets in. Someone can be entirely correct and still spend a lifetime looking at their own picture.
Khawāṭir: The thoughts that arrive on their own
Sufi teachers sort these by where they come from: God, a person's own wanting, or the devil. Telling them apart takes practice, and the rough test is simple. The pushy, flattering thought leaves a person restless, the other kind leaves them settled, and arriving loudly earns a thought nothing.
Murāqaba: Keeping watch over the heart
Al-Ghazali pairs this with sitting down at the end of the day and going over what happened. The watching stays light, closer to keeping half an eye on a pot on the stove while doing something else. Thoughts get caught early that way, before they harden into a mood, a grudge, or a plan that has to be undone later.
ʿUbūdiyya: Servanthood
Ibn Arabi holds that the highest thing a person can be called is a servant. The relief in it is that a servant does not have to run everything or settle every question; they take direction and go. A mind that has argued its own case for years finally gets to rest when winning stops being its job.
