The question is, if you change fundamentally, you affect the whole consciousness of man.
Napoleon affected the whole consciousness of Europe. Stalin affected the whole consciousness of Russia. Christ affected the consciousness of the world, and the Hindus with their peculiar gods have affected the consciousness of the world.
When you, as a human being, radically transform psychologically, that is, be free of fear, have right relationship with each other, end sorrow and so on, which is a radical transformation, then you affect the whole consciousness of man.
It is not an individual affair. It is not a selfish affair. It is not individual salvation; it is the salvation of all human beings of which you are.
