Query: This is for everyone

Even if you are not a yoga, yogi or especially if you are. It is incredibly well indexed and annotated so the book may serve as yoga instruction and a guide to applied yoga for medical conditions. Mr Iyengar, now in his 90's used yoga to gain his health when he was 30 or so. It is a very open document for the beginnner. It took me 9 months to complete the first two weeks of the books progression. A must have, like a bible, it should be in every home.
