Cats naturally have perfect tai chi. They display the Six Qualities in abundance. We humans can learn a lot from them.
The quality of fluidity consists of the subqualities of softness, expansiveness, and smoothness. Cats are both soft and springy at the same time, as well as smooth and graceful. That is why it is next to impossible to collide with a cat that doesn’t want to be collided with.
When they want to use force or resistance, cats know how to align their skeleton against the ground in the optimal way. That is why you feel the force of much more than just the weight of their fuzzy little bodies when they headbutt you.
Cats have a sense of balance humans can only aspire to. They maintain exquisite control of their center of mass. That is why it is almost impossible to pick up a cat that doesn’t want to be picked up.
Cats use their body in a coordinated, unified way. This is what allows them to coil their entire body like a spring and unleash it in a sudden pounce.
Cats are minutely sensitive to the minutest shifts of breeze, scent, light, sound, touch, and intent. This is what allows them to sniff your fingers while staying just out of range of being touched.
Cats are ready to spring into action at any moment, even from the middle of a deep sleep. This is what allows them to be so capricious and unpredictable.
