The quote is from an email I sent Jack a couple of days ago about the Sun Ancon Oxygenating Massager, henceforth referred to as the CHI Machine.

"A lady friend told me about it a couple of months ago, but couldn't tell me
the exact action, so I guessed a few, got her ankles and tried a few,
didn't work. Then back and forth L/R, and she went into the goldfish
wriggle, so it was obvious how it must work. But in fact there are at least
7 or 8 other ways of using the machine with totally different body
oscillations.
Try this one:
sit in a swivel chair with hips forward so you lay back lackadasically,
with feet in the slots somewhat sideways so the arches grip the central
hump comfortably, with the machine on the floor say 2 feet in front, maybe
more: splay the knees and let them relax wide apart, and palms between the
thighs comfortably: start the machine. Sooner or later you'll relax into
the very strange whole body oscillation and see what I mean."

To get the hang of that may take a couple or few minutes, but sit there motionless for a few minutes after the machine stops from its pre-set timer (set it to about 5 minutes at first, at most). You'll later notice your hips have loosened up, and you probably took some time before you could relax, and kept on relaxing over and over; that is letting go!
Now with this non-standard machine action, it is an education just how much one one involuntarily resists the strange body oscillations. And you will find the same blockages occur in MMO, but are difficult to discover. The best way to discover them using the machine, is to forget everything about anything erotic, especially the associations, and notice the body reactions.

The same will work sitting back in a lounge chair with buttocks just this side of the edge, or with any comfortable chair if you can sit on a capacious cushion. But a lay back recliner lets you half lie down, and with the machine just like a footstool, knees apart, the effect is enough not to want it to stop.
That swivel chair one is almost specific for enhancing MMO later. But the simplest non-standard way is to get everything ready as per instructions, then put one ankle over the other, as if sitting back with a brandy balloon and good cigarand your feet on the table, except you are flat on your back, preferably on a thick carpet, listening to relaxing music. In this position you can totally relax, and the ankles will stay locked comfortably.
The body oscillation is totally different, and asymmetrical, because the top leg will move much more then the lower one; hence two equal time goes on the machine one for each way, and a spell motionless after each; you will find the body reactions and blockages are different each way. In both cases the hips swivel, and the spine goes back and forth along its axis on the floor, and you nod, with a grin (optional, but you'll have one).
Happy wobbling
