Just another illusion?

To know God you should know yourself first. Without knowing that you cannot know God. That’s essential, that you should know yourself but when you know yourself, you know partly. The experience is not sufficient. The knowledge has to come. And the guru gives the knowledge about yourself. Now you have to tally it. You should find out whatever your guru has told you. Is it true or not? Is it correct or not? Or is it just another illusion?
