Which term describes the unchanging characteristics of universal forces?

The term that best describes the unchanging characteristics of universal forces is one that conveys the idea of constancy and stability. The correct choice reflects the notion that these forces maintain their essential qualities and do not fluctuate in response to external factors.

In this context, "unswayed" suggests that these universal forces remain unaffected by change, thus embodying a sense of reliability and permanence. This aligns with the concept that certain foundational principles in chiropractic philosophy persist regardless of the circumstances surrounding them.

Other terms such as dynamic and adaptive imply change or variability, and while these concepts can be important in different contexts, they do not accurately capture the essence of unchanging characteristics. Hence, "unswayed" is the most appropriate term to represent the consistent nature of universal forces in this philosophical framework.
