When doing the standing today I did feel like I had a pushing up feeling in the neck area but it also felt like my body was kind of hanging off from the top of the head. It almost felt like if you put a sheet over a stick, the pushing up feeling was the stick and the sheet draping down over the stick was the sensation of something from back top of the head just falling downwards around the neck and shoulder. Not sure if this is related to the pearls or maybe this is just related to the foot couple and the head neck and shoulders, or maybe neither and it's just a passing sensation.

The slack of which I speak can only be felt after cultivating coupled power and experiencing a bit of 'noninterference' in meditation. Conceptually, this definition is analogous to the slack of a geartrain. Slack for our purposes is defined as the range between 'softness-weakness' and 'strength-vigor'. This experiential range is subjective, and arises exclusively from interoceptive signals received from the deep core stabilizers. Chinese Martial Arts terminology at the start of this process is Jibengong or 'basic methods' and Shenfa, aka 'torso methods' as practice deepens.

When I was practicing today I did the standing, then did some wash face and arm swings. Then I did the standing. Then I did some of the punches/elbows and windmill kick (not sure if that is the correct name) and then the standing. Then I did the kicks that you just taught and the standing. Each time I would return to the standing the pressure suit feelings in the legs would get stronger.
