The purpose of that series of articles is to establish that there is a deep homogeneity between the teachings of the students who benefited form the Founder's contact on a direct and constant basis for a length of time before or after the war. Koichi TOHEI, Tadashi ABE, Gozo SHIODA, Morihiro SAITO are among these students.
To be fully useful, one should read first in Key points the 5 articles devoted to Ikkyo Shomen Uchi.
The pictures are extracted from Dynamic Aikido by Gozo SHIODA.
As O sensei explained in his book Budo and as Morihiro Saito used to explain it, Gozo Shioda clearly explains that Tori does not receive uke's attack. On the contrary it is tori who attacks and therefore performs shomen, uke rises his hand to protect himself only.
As one can see on O sensei's pictures and as Morihiro Saito used to teach, tori must bring uke down before stepping forward with his back leg. This is normal since in this movement, the back leg is used as a support to push.
Like O sensei and like Morihiro Saito, once uke is brought down, Shioda clearly states that one must push toward uke as if piercing with a spear. One must not pull uke as it is very common nowadays.
As O sensei used to do and as Morihiro Saito used to teach, Shioda's knees are strictly parallel to uke's arm and it is stated without ambiguity that this arm must form a 90º angle with uke's spine.**
Aikido is not a sport, it is a martial art which laws (takemusu) are in harmony with the laws of the universe. Studying them allows the practitioner to understand his place in the universe. Aikido was born in Iwama, O sensei achieved in that village the synthesis of tai jutsu, aiki ken and aiki jo.
The International Takemusu Aikido Federation (ITAF) brings to the practitioner the structure he needs in order to work as close as possible to the reality O sensei MU defined. The official national representations are the guarantee of a teaching faithful to the Founder's.
In modern Aikido, weapons are hardly taught, if taught at all. In O sensei's Aikido, on the contrary, aiki ken, aiki jo and tai jutsu are unified and form together a riai, a family of harmonious techniques stemming from one unique principle. Each techniques helps understand all the others.
Peace is a balance between a human being and the world around him. The true martial art's goal is not to become stronger than one's opponent but to find in that opponent a way to realize harmony. There is no enemy anymore as such, but an opportunity offered to reach unified ki.
