As i said before, I HAVE seen personally how ki exits the body and becomes a force, some sort of beam, and i FELT it being performed on me. So i would think that a similar technique can be applied to ki balls instead of ki beams dont u think? ofcourse this kinda thing doesnt happen overnight...... btw i dont spend all my time making ki balls, i meditate and try making a ki ball for like 15min a day, and i see the results, its not for knocking my opponents out with some kinda fireball, its about learning to manipulate my energies and to better understand ALL of nature and life.
