Forgiveness is the virtue of the brave.
The Congress fights not with violent but with nonviolent means, however imperfect, however crude the nonviolence may be.
Ahimsa is the strongest force known.
Satyagraha is search for Truth, and God is Truth.
Voluntary service of others demands the best of which one is capable, and must take precedence over service of self.
To my mind, Swaraj based on nonviolence is the fulfillment of the constructive programme.
