Meanning of ikkyo
Ikkyo represent the manifestation of your own control in life. It is expressing your existance where you stand.
Ikkyo is the basic of all pinningtechniques in aikido. It represents the square. Before you throw someone or when you hit or pin someone.
In Budo there is no other technique, that is so difficult in controling your opponent.
so I think, Rutger.
