I was asked a while ago to look into the etymology of the Karate-Do self-defence technique of 'Gedan Barai' - once by a British student (who had attended an advanced Japanese language course as he is a Solicitor) - and again by a Japanese student who was passing through the UK and had visited a few Dojos - saying some 'sounds' of the names of the techniques being used did not seem correct:
My view is that this transmission of culture is a) ongoing (and therefore a continuous process), and b) is a two-way street which must involve forgiveness and understanding. We must all help one another until our mutual understanding is correct. What is interesting is how philosophically different the 'Lower Block' is treated within Karate-Do compared to the 'Middle' and 'Upper' Blocks (which are explained merely as mechanical devices and not associated with the 'Conception Vessel' they pass through)! It is as if the 'Lower Block' is from a very old martial ritual! Finally, I was once told that the 'Lower Block' is not just a 'parry' or 'check' of an incoming attack - but is also a simultaneous 'Hammer-Strike' to the opponent's groin-area. Interesting food for thought.
