The movements used follow the principle of non-resistance: turning away when pushed, entering when pulled; all the techniques consist of these two elements of motion. In such a way the reed or the willow tree is able to withstand the force of the gale. There is great stability in the Aikido postures; in stillness, like that of a pyramid; in action, like that of a spinning top.

In practicing the techniques, one's partner is unbalanced by means of circular motions centred in the region of the hips so as to divert the direction and impetus of his attack. There is no dualistic opposition, but the partner's body, while under the control of one's own, is in complete unity with it. When the continuity of such circular or spherical motion is maintained, the grace and rhythm unique to Aikido appears.
