We walked into Ann Arbor last night to see Enlighten Up! Roger Ebert sums it up much better than I could. I will just add that you should not expect too much, but if you are curious about the yoga world - as I am because my wonderful wife does Bikram yoga on occasion - then you will like it. If you are a dyed-in-the-wool atheist or a dyed-in-the-wool theist of a particular flavor, you will like it less.
Recommended to those not dyed-in-the-wool
