Aiki (合氣, Aiki; literally: Joining Spirit) is a secret technique of ancient jujutsu.
Aiki is a Japanese martial arts principle or tactic in which the defender blends (without clashing) with the attacker, then goes on to dominate the assailant through the strength of their application of internal dynamics or Ki energy to affect techniques. Blending with an attacker's movements allows the Aiki practitioner to control the actions of the attacker with minimal effort. One applies Aiki by understanding the rhythm and intent of the attacker to find the optimal position and timing to apply a counter-technique.
