Very often people coming to hear me say afterwards, "Yes, all you say is very interesting, very beautiful, and I wish too that the world was changed. But how many think like you? How can you do it? How can it be done?" They come with that pessimistic remark, and I tell them, "One person comes into a country with a little cold or influenza and it spreads. If such a bad thing can spread, can not an elevated thought of love, kindness and goodwill towards all men spread? See then that there are finer germs, germs of goodwill, of love, kindness, and feeling, germs of brotherhood, of the desire for spiritual evolution, which can have greater results than the other ones. If we all have that optimistic view, if we all work in our little way, we can accomplish a great deal."
