In Japanese martial arts, the concept of internal power is known as aiki (commonly translated as "joining energy"). It's a term that has as many definitions as it does practitioners. Thanks to the popularity of Aikido, most people characterize aiki as merely blending with the opponent's force and redirecting them into a soft lock or throw. However, as an instructor of Aiki Jujutsu I tend to define aiki at another level. Ultimately to me, aiki is a pre-conditioned state of being. Internal power is generated in the way you stand, the way you walk. Aiki is learning how to use the body in its most efficient state so that anything that comes into contact with it is affected. In a defensive scenario, aiki is the systematic process of receiving the force of the attack, processing it and returning it through the point of connection. True aiki is characterized by instant kuzushi (off-balancing) that affects the attacker's entire body. This is accomplished through proper breath control, timing and a relaxed yet focused structure within our own bodies.
But the concept of joining energy is hardly unique to martial arts. Everything in the universe is comprised of energy, so in reality whenever you come into contact with anything you are joining your energy with it. In the healing art of Reiki, you are joining your energy with that of the recipient to enhance the body's natural healing powers. This may sound like pseudoscience but the principles of Reiki are instinctive in all of us. When you injure yourself, your first reaction is to grab whatever you just injured and apply pressure. Often this is accompanied with thoughts like "Please stop hurting" and shortly after, the pain begins to subside. This is the basis of Reiki. The body intuitively knows what's wrong and has the power to heal it. However, if something is off (such as Chakra misalignment which is very common) then the healing powers may be hindered. That's where the Reiki practitioner comes in. When a Reiki practitioner lays their hands on the recipient, their healthy energy overpowers and supercharges the recipient's energy flow to assist in the healing process. But how does it work and how is this even remotely related to Aiki Jujutsu?
