Start by doing:
Ground and center. You could start by visualizing your energy extending down into the Earth like the roots of a tree, connecting with its energy. There are other methods. This exercise is intended to balance you
Recognize the flow of psi. Psi is energy and can be sensed, but for now it's enough to know that energy exists within you and flows through your body all the time
Move your psi ball. Move it just like you moved the psi from your solar plexus. This time it won't be in your body, though. This can take practice; you will get better
Hope i helped.
