I'm adding to this to give a quick hand to people who don't yet know how to connect with their peronal energy (chi) but are too shy to say :D
This is what you can do..
Sit in a comfy positin and relax. Vigorously shake out your arms, hands and fingers. Then, put your hands in the prayer position, only about an inch apart.
Close your eyes and focus on what you can FEEL between your hands. Usually, at first, you will feel a tingly sensation. This is the bio-electricity of your chi. When you have established this, start over again.
After a few goes, you will feel a force between your hands. It feels like two magnets pushing apart. This is your chi getting stronger.
When this is easy, try squashing it, stretching it, moving it about. You are now manipulating your energy.
With practice, the force will grow. Mould it like clay. Soon you will be able to create a sphere from it. This is called a psi ball.
A lovely way to practice this is with a friend. Sit cross legged opposite each other and put your palms almost against each other's. You will feel their chi, they will feel yours. Also, you will feel the mixture of the two energies. Now you are an energy worker ! :D
