darning, repair, mend, trim, tidy up, adjust
繕 centers on fixing or improving something by hand, especially with thread or careful adjustment: mending clothes, repairing damage, tidying up, or adjusting details.
繕 combines 糸 (thread) with 善, which likely contributes the sound ゼン and the idea of making good or right. The character suggests using thread to make something good again.
Thread 糸 and good 善 come together: using thread to make something good again, like darning a sock or mending a tear.
For ゼン, imagine a Zen monk patiently mending a robe with thread: Zen -> ゼン, and the careful repair brings peace.
