Before starting to work with the fire element directly, for instance, by letting it enter your aura, chakras, or accumulating this energy in your own field, I advise exercising a bit with energy work. By that, I mean that we will learn to feel, accumulate, consciously use, and send Prana/chi, or if you wish, “the universal life force.” Prana is the reason why things happen, move, and live, so it gives them motion and fills them with life. It’s everywhere, so we don’t need any special divine channel to generate and gather it.
We can generate it through physical exercises like yoga or tai-chi or by sensitizing hands, concentration/visualization, and breath work.

There are two main purposes for gathering Chi. We can do it to set our intentions into motion and make them happen, or we can initiate a transformative process (inner changes) by doing this. Both can be used for magic(k), spiritual growth, or healing.

Wait, but how is it connected with fire? Because setting things in motion, keeping them alive, inducing changes, feeling with drive, healing, and spiritual transformation are things we usually associate with these processes. Additionally, it is better to learn first how to wield and feel neutral prana, which is safer than rushing with the elemental energy of fire.
