Non-violence and cowardice are contradictory terms. Non-violence is the greatest virtue, cowardice the greatest vice. Non-violence springs from love, cowardice from hate. Non-violence always suffers, cowardice would always inflict suffering. Perfect non-violence is the highest bravery. Non-violent conduct is never demoralising; cowardice always is.
Whilst I may not actually help anyone to retaliate, I must not let a coward seek shelter behind nonviolence so-called. Not knowing the stuff of which nonviolence is made, many have honestly believed that running away from danger every time was a virtue compared to offering resistance, especially when it was fraught with danger to one's life. As a teacher of nonviolence I must, so far as it is possible for me, guard against such an unmanly belief.
It is the duty of every cultured man or woman to read sympathetically the scriptures of the world. If we are to respect others' religions as we would have them respect our own, a friendly study of the world's religions is a sacred duty.
