Feel the energy swirling and building up between your hands. Make the energy into a ball between your hands, making it denser as you add energy.
The sensations you feel may be very slight. Trust your sensations.
Pair off and one person put their hand into the middle of the others psi ball. Feel how it changes when your hand enters the ball. How does it feel different to your own? Swap pairs and feel the differences between different peoples energy. What colour can you relate the different energies to?
Each person starts by creating his or her own psi ball. Then combine all of the psiballs into the centre of the circle. Each person continues to add energy to the centre. After a few minutes, discuss how each person perceives the energy.
Experiment with shape, temperature, emotion and colour to make your ball react to your thoughts.
Psiballs don’t have many practical uses - their primary purpose is to learn basic energy perception and control. Beyond that, they can be used in all the same ways energy can.
