By 1969, Ellsberg began attending anti-war events while still remaining in his position at RAND. In April 1968, Ellsberg attended a Princeton conference on "Revolution in a Changing World," where he met Gandhian peace activist Janaki Tschannerl from India, who had a profound influence on him, and Eqbal Ahmed, a Pakistani fellow at the Adlai Stevenson Institute later to be indicted with Rev. Philip Berrigan for anti-war activism. Ellsberg particularly recalls Tschannerl saying "In my world, there are no enemies", and that "she gave me a vision, as a Gandhian, of a different way of living and resistance, of exercising power nonviolently."
