All magical systems and schools work with elements. In the west we call them air, fire, water, earth and spirit.
We can see them all around us, feel their impact in our body and mind. But what we can sense is just a reflection of what they are in reality! So, if you want to understand them, you have to feel them within. Air carries the archetypal properties of spirit to the physical world. It is associated with the operation of Separation. As soon as we call to mind the air element within the body — the air in our lungs and other body cavities, even the gases dissolved in our blood — we’re immediately aware of the breathing, aware that air is flowing rhythmically in and out of the body.
