Maʿrifa: knowing God firsthand
Sufis use this word for the knowing that comes from meeting, the way you know a friend rather than knowing facts about a stranger. A meeting like that leaves a mark that does not wash off, even in the flat stretches when nothing is felt. So when an old pull returns, it meets someone who has already been somewhere, and the mismatch between those two is what stings.
He loves them and they love Him: God's side moves first
Sufis keep coming back to this line from the Quran whenever the question is who started it. A person's turning toward God feels like their own achievement, until they look back and see they were being drawn the whole time. That changes what a bad stretch means, because the hold that keeps them was never their own grip to begin with.
Ghafla: heedlessness, God slipping out of mind
The word covers plain forgetting, the fog that settles without any argument or refusal. Nobody schedules it; the mind fills with other business, and old attachments walk back in through the gap. So people end up somewhere they swore they had left, without ever deciding to go.
Shirk khafī: hidden idol-making
Sufis name with this the quiet version, where something small takes the seat God had. A rule, a habit, a reputation, a routine that promises safety: each can start running a person who never agreed to hand it the job. Going back to one of them gives over the room again, and whatever moves in begins giving orders.
Ḥurriyya: freedom, a heart owned by nothing made
Sufis count freedom as a station, reached by belonging to God alone. Serving one Master costs less than serving a hundred small ones, each with its demands and each with its own way of punishing you. People slide back anyway, because the old arrangement is familiar and its price is known, even when that price was everything.
