Aiki Age 'shape'?

Speaking for Josh, I believe he is referring to different shapes of aiki age alias kokyu-ho.

Allen Beebe wrote: The 法 (Ho) in 呼吸法 Kokyuho is commonly defined as "law," such as a "law of nature" or "Buddhist law."

Also, though in the Chinese reading (it differs little in this case) -- in 兵法 Bīng Fǎ, Sun-zi's famous treatise on war. 法 is closer in reference to the Greek techne which we now separate into two aspects "art" and "technology" -- but they did not. And so our technology became ugly and our art useless.

There is a lesson here, I think.

Allen Beebe wrote: Of course Aiki Age and Aiki Sage, on the surface at least, appear to be a bit more discrete in their directional reference than Kokyu . . . on the other hand, if they are not linear in nature then where does the Age or Sage begin or end exactly? Perhaps there specificity is more of a referent of relative convenience rather than an absolute.

I identify aiki with the manipulation (法?) of pure shears. Pure shears exploit the gyrational qualities of structures, statically and dynamically. Juji or the perpendicular principle of action, alters the eccentricity of loads on the structure, to create shears from existing poised loads without altering them directly.

A wave is a dynamic shear translated through a medium. In a wave, the water at the trough edge is drawn under and up the rear of the swell. The crest is drawn over and down the face. This is the principle/law/method of aiki age and aiki sage/inyoho/kokyuho etc...

If pure shear is present both complementary actions are in action simultaneously in every case -- but, as in the breaking wave (aiki sage) or the tsunami's lengthy drawout (aiki age) -- not always obviously coincident -- dare I say, one is quite often omote and the other ura.

"A wave is a dynamic shear translated through a medium. In a wave, the water at the trough edge is drawn under and up the rear of the swell"

I've been enlightened! I now know the next step to internal bodyskill!

Ah, but can you surf ? -- That's the question.

The topic was the relationship of the two principles (age - sage)and their relation to the shape of the action in the OP.

Is my observation wrong, in your view? If so, how would you better describe it ?

That's very interesting, Erick. Could you please elaborate on juji altering the eccentricity of loads "without altering them directly".

Thank you,
Alex.

"Not altering directly" in the sense of neither adding to nor diminishing ... An applied load at 90 degrees to another load ( or pair of opposed loads poised statically), alters the eccentricity of the load without changing its magnitude -- neither opposing it or adding any extra energy. To shear a structure in this manner the necessary applied load in Juji is very small in proportion to the typical poised static loads (e.g. -- your weight poised against the earth's resistance at any support joint).

An oscillation applied (or the static "shape" equivalent -- like a shifting standing wave -- tegatana -- see the OP image again) "pushes" that wave-like eccentricity displacement (irimi-tenkan principle) through the structure until it finds a support joint that is incapable of recovering from the displacement and that progressively buckles the whole thing -- either in compression (aiki-sage) or in tension (aiki-age) or in both simultaneously (tenchi). Biomechanical manipulations also play into it -- but only because the body is naturally attuned to its critical vulnerability to these things and reflexively responds to those if they occur at a resonant frequency (e.g. -- furitama or tekubifuri) before the target can consciously react.
