Concentration, intention: Naruto has the idea right, but not the right practice

I will translate the important message from "virgin kung fu" in the future.
The important lesson is:
While doing San Ti standing,
Stand on top of something at least 3 inches away from ground.
e.g. brick, chair.
Focus on a point in front of you.
Breathe in and out of feet. Focus breathing from the ground
that is separated by the object you are standing on.
Same time: breathing in and out of fingers, palm that is
pointing at the "point in front of you"

Imagine heavy air particles between my hand and the point.
The push and pulling motions should affect, compress those
air particles, molecules, creating pressure
