The kanji 巻 primarily conveys the idea of "to roll," "to coil," or "volume." It suggests a form that is wrapped around itself, or a unit of something that is gathered or bound together. This can refer to physical objects like scrolls or rolls of paper, or abstract concepts like the chapters of a book.
