Ranai 乱合 (9/9) Ranai in the Dojo
This final video isn’t a demonstration... it’s just practice (with Andrei).
And practice is what (I believe) Ranai was made for.
But what was it ACTUALLY made for, and when?
It's not on the SMR densho lists, but it's likely to have existed as an oral teaching by the end of the Meiji period.
It seems reasonable to assume that a sequence of techniques known by that name existed by the time of Shiraishi Hanjiro (Shimizu Takaji's teacher). I speculate that he would have had a good idea about the purpose of Ranai.
It seems that Ranai is a composite summary of many other techniques in SMR, and as Pascal Krieger Sensei wrote, it has the effect of "boiling the water" on the practitioner.
So if it is a "summary" Kata that transmits fighting spirit, Shimizu Takaji must have thought this an excellent choice to be part of the Seitei selection.
I'll conclude with my personal speculation:
There's no one true way to do Ranai. There is, however, a spirit to strive for.
If you push Ranai hard enough, the structure starts to strain.
Mistakes appear. Timing collapses. Different possibilities emerge.
It teaches you to remain calm even when you're tired and movement gets sloppy.
It teaches you to keep the form while also letting go of it.
In other words, it teaches you to harmonise with chaos.
Ranai is not so much about teaching, but more about forging.
Why do you do Ranai?
