Aikido ki energy
lthough it’s a part of the very word aikido, ki lacks a definition that everybody doing aikido agrees on. On any internet aikido forum there are countless postings about ki, and almost as many views on it. Here’s mine.
Again, since ki is part of the word aikido, it is of great importance in practice. When we do aikido, it should be done with ki as a prominent ingredient. Ki flows, and the path of this flow through an aikido technique is the actual technique – more so than any hand, arm or body movement. Ki comes first, and the body follows, like a boat floats on the current of a river.
This is true for both tori, the defender, and uke, the attacker.
