What is magic?

What is magic?
My friends say it doesn’t exist.
But I can feel it, though not with my hands.
I can hear it but not with my ears.
I can see it, not with my eyes.
Taste and smell but not with my mouth or nose.
From all senses, maybe a sixth sense or no sense at all.
It is everywhere and nowhere.
It moves like fluid, it swirls all around me, inside me.
I can sense it in others, most are dim, some brighter, more powerful.
Now I need to learn how to understand it and how to control it.
