The photographs for the project are taken on glass plates using the wet collodion process, a photographic technique dating back to the 1850s. The photographs take on another dimension with the spoken words that accompany them. The text provides an intimate and enlightening account of each person's personal journey. Beyond the physical postures Yoga: The Secret of Life delves deep into the purpose of our existence and how to live a happy and fulfilled life.
