You're talking about energy flow.
Energy Flow is one the very basics of magic. More or less being because magic is the very changing and shifting or energy. That's all it is. Energy Flow is to practice controlling the flow of internal energy. Internal energy is simply the energy generated within your own body, which it is always flowing, and it is possible to control that flow. Working on energy flow helps exponentially when working with energy in general. First off you have your chakras, chakras generate energy, this energy rotates through out your body, and in some places around your body (an example of this is aura). You must feel this flow before interfering with it, and once you do, you can consciously change its direction, magnitude, and attribute. This is the basics of energy manipulation.
Now then, energy flow, part of energy manipulation, is part of a segment in magic called Direct Magic (what Eclipse used to specialize in). Direct Magic contains energy manipulation, and a bit of divination. Divination is psychic development, how this ties into Direct Magic is something called psionics.
Energy flow is a very common and studied subject here. Since you know the correct phrase, you can learn about developing it a bit more.
