Darrell Anka's Transformational State of Mind

Anka: It's like falling into a very dynamic day, dranr with images and feelings and concepts coming very quickly in a telepathic sort of way. And it takes me a moment to sort of snap back, but then i'm more energizing. Often starving, really hungry. I canna understand why he might say there's sort of this idea, like in fiction, that using magic sort of drains you. Otherwise it would just be too easy to do magic all the time. Yes?
