"Experience makes good people better."
Seriously, I am the only person I know who's read this "best baseball book ever" and not liked it. I just, ummm, didn't get it. But don't let that stop you from reading it. Maybe i'll try it again in a few years. For now, the reminder that "Suffering is what brings us toward happiness" was all I needed from this book.
Bikram (the man) says pretty much the same thing, several times over the course of the recorded class that I occasionally practice with at home. (He also hammers it in his books, particularly the newer, orange one.) For all of the disenchanting stuff that I hear about the man, he seems fine in the class. If you haven't listened to the CD class, I highly recommend it. It's available at iTunes, and probably your studio.
