Humankind has to get out of violence only through non-violence. Hatred can be overcome only by love. Counter - hatred only increases the surface as well as the depth of hatred.
Experience convinces me that permanent good can never be the outcome of untruth & violence. Even if my belief is a fond delusion, it will be admitted that it is a fascinating delusion.
In the application of the method of non-violence, one must believe in the possibility of every person, however depraved, being reformed under humane and skilled treatment.
