Anyone who has ever studied Martial Arts has probably heard the words Do and Jutsu many times. Many seem to think they mean the same thing (you hear allot about kendo and kenjutsu etc).
Do is the Way.
Jutsu is the technique.
If your Martial Are specializes in sword techniques it is a Ken Do and other techniques are a Jutsu. If your Martial Art specializes in hand to hand it is a Karate Do. See?
I choose the Ai Ki Do - The harmony energy way. Every new Martial Art and Jutsu I learn I perfect in Ai Ki.
