I bought Mind Control by Ashida Kim, it does really teach Mind Control but is an introductory to mental powers, one is mind reading.
This 9 powers have a hand postion, to activate qi channels, in his other book which is at his website they explan the positions more clearly.

from what I have read, Ninjutsu came not just from the kungfu fighting systems, but by chinese, philosophy, war strategy and martial arts(kungfu I guess).
