Like Jeanne, i see partner dancing, particularly tango, as complementary to aikido in terms of connection, lead& follow, and maintaining maai & extension. Tango has very clear definitions of partnering which can also translate to "when nage does this, uke does this...."
I practice vipassana meditation daily, and tai chi,also practice the energy work of Robert Nadeau Sensei, and intensive Concious Embodiment(www.conciousembodiment.com
) with Wendy Palmer Sensei. Wendy is trying to offer a CE/meditation retreat for this summer which i cannot make, i used to do intensive meditation retreats regularly. Would really be interested in doing something extended involving all of these practices together!
