輪

• Concrete: A wheel or ring; may occasionally function as synecdoche for the vehicle itself.
• Mechanical/Physical Motion: To revolve, spin, or turn on an axis.
• Sequential Order: Turn-taking; a predictable sequence where participants or duties rotate.
• Temporal Recurrence: The returning of seasons, phases, or recurring events.

• Noun: A wheel; a circular object/ring.
• Verb: To revolve; to rotate; to cycle through a sequence.
• Adverbial Modifier: Used to indicate that an action is performed "by turns" or "sequentially."

• 輪 vs. 圓 (yuán): Contrast between movement and shape. 圓 denotes geometry, circularity, and completeness; 輪 denotes the mechanics of rotation and the process of cycling.
• 輪 vs. 轉 (zhuǎn): While both involve turning, 輪 emphasizes a consistent cycle or a return to a starting point, whereas 轉 often implies a change in direction, a pivot, or a transformation.

• Variants: 𧵖, U+8F6E.

In Buddhist or cosmological texts, the physical "wheel" is frequently used for metaphysical concepts, typically representing the law of causality, the cyclical nature of existence (Samsara), or the propagation of doctrine (the Dharma wheel).
