Visualize the energy in your body.

Project the energy out of your body but not completely, just enough to have it about six inches over your skin.

Now by visualizing the energy in different construct shapes over your body you will be able to augment yourself with astral energy.

Visualizing giant fists made out of your energy over your hands allows you to augment your strength in your punch, visualizing a visor of energy over your face you can augment your vision and add graphics to what you see.
