I thought you might find these interesting in regards to a Chinese Martial artists experience in learning Daito ryu's internal aspects. Once again, to express the commonalties of all the Asain arts- from an internal point of view. ....

Daito ryu basically consists of three types of technique or three methods of using ones own body and manipulating another persons. Jujutsu, (edited) aiki-jujutsu: the relaxation gives the opponent has nothing to push against while the spiralling movements twist and lock up the joints up to the spine.
and then aiki no jutsu:
Taking control of the opponents spine, breaking their root and throwing them using any point of contact. like a hand on the shoulder, a forearm touching an elbow or whatever. a tiny, fast, barely perceptible circle and you get lifted onto your toes and thrown on the ground.
