I'm sorry to have to ask, but what do you mean exactly? Seems like a cliffhanger ending to a blog entry.
Try this experiment using 1/4 to 1/2 power only (you need a nice uke- buy the uke drinks later!):
1) Get in a traditional karate position to punch. Focus in solely on your punching hand when you punch a person in the chest.
2) Get in that same position and focus solely on the drawing in hand.
Ask your uke if there was a difference and what the difference was. The change from focus is similar to the issue of intention.
This topic can easily get lost in words. When you can feel the difference from things like this exercise you begin to enter into the depths of Irimi. I would highly recommend reading the book "Karate and Ki" for more detailed and better descriptions of this topic than I am currently capable of providing you with.
