The Swiss aikido web

"ai" means harmony, union, or coming together. In Aikido, it refers to blending with an opponent’s movement rather than opposing it head-on. Instead of collision, the practitioner seeks connection, timing, and alignment, transforming conflict into cooperation.

"ki" is often translated as energy, spirit, or vital force. It represents both physical vitality and mental presence. In Aikido, cultivating ki means moving with calm focus, relaxed power, and awareness - allowing techniques to flow naturally and efficiently.

"do" means "the way" or "the path". It implies a lifelong journey of learning and self-development. In Aikido, practice is not only about technique, but about personal growth, discipline, and applying its principles beyond the dojo, in everyday life.
