Face a single foe as if you are facing ten thousand enemies; face ten thousand enemies as a single foe - Morihei Ueshiba

In our techniques we enter completely into, blend totally with, and control firmly an attack. Strength resides where one's ki is concentrated and stable; confusion and maliciousness arise when ki stagnates.

Never chase after opponents

In Aikido we never attack. An attack is proof that one is out of control. Never run away from any kind of challenge, but do not try to suppress or control an opponent unnaturally. Let attackers come any way they like and then blend with them. Never chase after opponents. Redirect each attack and get firmly behind it.
