Re: Two centers making a connection or one- in a bujutsu body?
It is simple really. Presenting an obvious centre to your partner is creating an opening that can be exploited or manipulated. In sword - see Yagyu Munenori - a distinction is drawn between attacking the seen and unseen. Too obvious a preoccupation with centre is the 'seen'. This does not mean not to have centre, but instead advocates less attachment to it.
