There is only a world if there is a me, lot of people say in the Advaita. I don't buy that. There is a me and there is a world. We can discuss this endlessly. But is is important? Buddha didn't want to discuss the existens of god, because, he said, it only distract us from what is realy important. You and your way to realization.

Christians, he said, where a head because christians had only one live to succeed.
