Once you are able to project energy externally, it is a good idea to begin working on moving energy through your body so that you can have better control over where the energy is within. this will allow you to project it more effectively, and to have a stronger connection, and sense of what is going on inside of you.
In order to do this all you would have to do is find a comfortable space where you will be able to focus on this exercise, and then go through the process of focusing your mind, and enter a meditative state. From here make an energy ball within your hands, and it would be a good idea to work at this energy ball until it is a nice strong dense construct of your energy. This will allow you to keep your mental focus upon it, and allow you to be able to feel it as it flows through you.
Once your energy ball has been realized visualize it flowing into one of your hands, then moving up your arms, and then into your heart space. While you are visualizing this take note of the feeling of the energy ball moving throughout your body, and memorize this feeling, and will that it takes to move that energy through your body. Once this energy ball gets to your heart space begin visualizing it moving to different parts of your body, so that you will be able to practice moving at around.
I would keep up with this for a couple minutes, so that you can really strengthen your control over these parts of yourself. Allow it to flow to every part of your being, while focusing upon it, and continue to make notes of how the energy feels as it moves from one place to the other. Remember to also take time to focus on moving it from your heart space to your feet, and back again. It will most likely be harder for you to move it between your feet and your Center because that is not done as much.
Once you are done with this exercise simply allow the energy that you were focusing on to diffuse back into your energy system. Then exit your meditative state slowly, and then go on with the rest of your day.
