People make fun of the old "elements" - earth, air, fire, water. But all they are is the use of phases - solid, gas, plasma, liquid - as symbols, metaphors. Once this metaphorical thinking was thought to work like a science. Now we know it doesn't. It's a myth. But myths can tell us about ourselves. They tap into dreams and change us. There's nothing wrong with using plasma as a metaphor for inspiration, will, action, change.
