Most people's attention is "outside that attack" or one could say "on" the attack. Their attention is on grabbing the arm or getting out of the way of the strike. The attack is not the same thing as the attacker's center. The attack originates at the attacker's center, that is where the attacker's mind is, that's where you place your attention. The attack itself is unimportant, it's controlling the mind of the attacker that allows you to do the physical technique. That's why the "reactive mind", the one that thinks in terms of speed and timing etc is not what O-Sensei was talking about. Your mind is already "in", not on the attack but inside the attack. If you understand this you can put the would be attacker in a position in which he will feel that he can't attack you because on some level he perceives that he has already lost.
In light of this worthwhile advice, and the expansion of selfless subjectivity apparently involved in both ki musubi and contemplative experience, this is appropriate:
"God is an infinite sphere -- whose center is everywhere, and whose circumference is nowhere." Nicholas of Cusa.
In other words, there is but one and only one center; he who sees the "other" instead of a slightly more remote part of himself -- is not standing there.
