When you are distracted from preserving your own heart. Allah does it for you. This is why doors you insist on walking through close on you. What you feel, all of it, are guiding you to what you weren’t doing that Allah does for you.
To sit through such feelings is difficult because you are walking through the effects of the wounds, that hold up the very veils preventing you from seeing the distractions for what they are.
Allah wills to give you sight where you are blind.
