This string has taken many interesting directions - mental, emotional, spiritual and push hands technique. On the latter, some people consider "resistance" a dirty word in Taiji. They hold that yielding is the only real way. So how do you define resistance? T.T Liang writes that ward off energy is like water holding up the hull of a boat. I like this description. It implies a springiness that is proportional to the energy received. I show my students that taiji is not totally floppy and not totally rigid - it is springy and tenacious. With this type of energy used then it is correct to yield - but as described by someone above, the energy returns to the pusher through the other side. So should we blacklist the word "resistance" from our Taiji vocabulary? I don't think so. The same holds true in life - just because you're peace loving doesn't mean you should be a door mat. Balance is important in all aspects of living. Taiji is a great teacher.
