During 1981 he was invited to express his proposals in various public rallies in European and Asian cities, visiting Madrid, Rome, Barcelona, and later Mumbai (India) and Colombo (Sri Lanka), before returning to Paris, and later San Francisco (California) and Mexico City. He explained with particular force the position of nonviolence, manifested in the overcoming of suffering, the human treatment of others and the attitude of not searching for those to blame. Aspects of these talks relevant to his thought were published in the book “"Silo Speaks"”.
