I read about Jill Bolte Taylor in an essay written by Ann-Marie Priest in The Best Australian Essays 2009 edited by Robyn Davidson. Thanks to the internet you can see Ms. Taylor, looking quite well, in this presentation in 2008.
Ms. Taylor's description is identical to many others who took LSD. What's interesting is that even though she recognised her experience stemmed from a physiological condition (a stroke), that didn't diminish the value of it. Her book My Stroke of Insight: A Brain Scientist's Personal Journey has the details.
My explorations occurred at a much younger age, but the insights are still unfolding and continue to provide the foundation for my day-to-day behavior. I can only hope my stroke, if/when it occurs, is as elucidating as the experiences of my youth. Something to look forward to!!
