RE: The Emphasis on Ki
These are the main differences in training approaches between the various Aikido schools/ryus/styles.
Some emphasise a wide variety of techniques in Kyu grades & only introduce Ki extensions in the Dan grades,
while others emphasise Ki extensions (on a handful of basic techniques) in Kyu grades & only begin exploring the wider range of techniques in the Dan grades.
There are pros & cons for each approach. My Ryu, Tendoryu, adopts the latter approach. For Kyu grades, to develop our Ki extension from our centre, we practise on 4 basic techniques: Ikkyo, Shiho Nage, Kotegaeshi & Irimi Nage continuously.
Only from Shodan that we begin exploring the other less-known techniques.
RE: Ki a mysticalmagical thing??
I believe there is Ki in everyone of us. We just have to learn to develop, control & project it.
I believe we have electricity
in us manifested by chemicals, from the fuel we eat and drink, which coordinate via brain neurons and connections and the cortex to the muscles which have memory, given enough practice......
