A documentary explaining that yoga is not just a set of PT exercises to loose fat and de-stress, but a vast and complex technology in constant development and improvement since the Vedas written 4 000 years ago. A technology with theoretical underpinnings (cosmology), marketed differently in various times to various audiences, but always promising the full realization of human potential to attain freedom: freedom from constraints, freedom of creation, freedom of knowledge, freedom of life and death. Why only Hatha yoga has gained traction in the West? Why is yoga unknown by most Indians? What can we do with this technology today, in the XXI century? The film offers perspectives, data and thoughts from current scientists in the US, Russia and India, as well as interviews with leading practitioners and teachers.
