Sri Krishnamacharya's 

first book:

Yoga Makaranda 1931

A few photos from one of the few remaining original texts.  After nearly a month of searching, I found it in the Sanskrit College Library in Mysore, India.  Thanks to my fellow yogis for encouraging me to complete the task of photographing all the pages.  You can see my shadow in one of the photos.  My Bangalore yogini friend, Sujata, was to translate it into English.  Turns out Krishanmacharaya Yoga Mandiram is currently working on the translation so we did not complete the project ourselves.
