During the following winter of 1994-95, the Israeli filmmakers traveled to both Tihar and to the Baroda Jail in the India state of Gujarat, at which Vipassana courses had also been conducted. There they conducted and filmed extensive interviews with jail officials, including Kiren Bedi, and inmates from many different countries who participated in the courses. The result of these efforts was an extremely powerful 52-minute documentary film entitled Doing Time, Doing Vipassana. The film describes the way in which Vipassana has been sucessfully used within the Indian prison system to dramatically change the behaviour and attitude of the inmates and jailers who participated in the courses and, thereby, improve the entire atmosphere of the prisons.
