Ok, here's the problem. I can make a psi ball, but it doesn't seem to last at all. It usually just disipates (not too sure about the spelling) on its own after I move my hands away and stop concentrating on it. I've read on shelling, but still can't seem to make the psi ball stay, even for a few seconds. (meaning I can't shell the psi ball :( ) I have not much problems in manipulating the psi-ball, i.e. temperature, making a cold or hot psi ball (visualising using a different source of energy), or a big or small ball. The main problem is making it stay a ball even after I've done manipulating it.
Please help :(
