Most of us see the world as this vast domain and we are but one person
But let us analyze, the Rebbe certainly changed the world, how?
In fact all the great Rebbes before him did – how?
The answer is perplexing i.e. people perceive two worlds which are superimposed on each other.
The first world is the mind that somehow adds up all the dots of reality quickly – seven billion people – lots of land etc. etc.
But then there is a much much smaller world, which is the heart – the world out there is really the world in here.
In other words, say a child is God forbid abused, then the world outside there very much gets superimposed based on the world inside here, and he perceives a hostile angry world, and he usually becomes hostile and angry as well.
