It is not an easy read. If your last memory of biology is from class 10 then it will be that much harder to read this book. Cells, membranes et al. it is a good attempt at explaining the synergy between mind and body, energy and matter. Don't take this book with you on a vacation, but do read it when you need some brain flexing.
Oh yeah and I did not read the last 2-3 pages as I still am in that space where I cannot digest science mixed up with philosophy and nirvana.
