there is a tiny thing called 'ki' that I see demonstrated every time I train. Now we have had numerous discussions as to whether ki exists and I am not interested in beating that drum. Suffice to say, aikido without ki becomes ai-do.
There are two wild cards in Aikido...one is the development of Ki energy and the other is the development of precognition.
I'm perfectly happy to accept the existence of both, but I believe they are extremely rare.
In a book on the Chinese internal arts Bruce Frantzis talks about going to Japan on his way to China and witnessing some paranormal force in the Aikido of Ueshiba...but he also makes a point of saying this force was nowhere to be found in Ueshiba's inner circle of students.
Ueshiba also made claims to a psychic precognition of any attacker's intention, making it easy for him to adjust his defense accordingly.
Now the only evidence I've seen of this in a living person was at an Aikido demonstration several years ago given by a Japanese master in his early sixties...cant remember his name sorry.
He performed this one stunt where he would stand passively and invite two LARGE members of the audience to try and lift him off the ground, with no apparent resistance on his part. They couldnt do it.
And another trick involving him kneeling at ease and having several people try to push him over from all directions. Again, he wouldn't budge.
This was a very impessive display of postural stability to say the least, almost magical, but the rest of the demonstration was horrible...the usual over commited attacks, arms freezing in mid air, nobody grabbed for his legs, no kicks, etc.
It could be that Aikido isnt very effective without these two wild cards.
I really dont know.
