This was inspired by the guest post, Observations about Ukemi.
Picture this: Uke attacks yokomen. Nage enters irimi and, unexpectedly, tenkans away from uke, seemingly losing his center connection. Nage then turns to face uke and, decisively, cuts uke’s sword arm, now descending through empty air.
The technique that follows is irrelevant.
If Aikido is all about maintaining connection, why does that entrance work?
