Qi

In traditional Chinese culture, qi is an active principle forming part of any living thing. It is frequently translated as "energy flow," and is often compared to Western notions of energeia or élan vital (vitalism) as well as the yogic notion of prana. The literal translation is "air," "breath," or "gas"

Sympathetic and parasympathetic divisions typically function in opposition to each other. But this opposition is better termed complementary in nature rather than antagonistic. For an analogy, one may think of the sympathetic division as the accelerator and the parasympathetic division as the brake. The sympathetic division typically functions in actions requiring quick responses. The parasympathetic division functions with actions that do not require immediate reaction. Consider sympathetic as "fight or flight" and parasympathetic as "rest and digest".
