My Stroke of Insight by Dr Jill Bolte Taylor is her personal story of how she suffered a stroke and her subsequent recovery.
Whilst this is not a Tai Chi book it is a worthwhile and fascinating read. There is the usual stuff about the Brain and how it works, but for me what is really interesting is how she describes what is happening to her as her mind deteriorates in the course of a few hours. As the left side of her brain shuts down she compares her state to being in Nirvana.
The last chapter is called Finding Your Deep Inner Peace and she posits that we can use the skills of our motor output systems to transform our perspective to the present moment.so for example, this could be Tai Chi, Yoga, Walking etc.
This book is well worth reading.
