Ok I am going to try and teach you how to make a psi ball.To start put you hands together.Make your palms face each other.
Try to visualize energy flowing into your hands.If you do this right you hands should start to feel a slight breeze,get warmer,colder,twich.If your hands get to hot you a forcing the energy there to fast.It should be natural.Once you feel the energy in your hands try to push it between them.Then repeat this prossess and make it stronger.If it gets strong enuff you will start to see it.Hint try to keep all energy in between your hands.
