Fire in the mind = manic-depression.
I actually enjoy the artwork here. For once this is not a sarcastic caption. I wonder who drew it. If someone who was diagnosed with manic-depression (note: this is no longer the correct clinical terminology, symptoms of manic-depression are now often diagnosed and/or labeled as bi-polar) drew this I would say it is enlightening, interesting, and perhaps insightful. If someone who has no experience with mental illness drew this I would question why this imagery came to mind.
