In plain words
… I am in the light means you think you are. The light is in me means the one others think you are. I am the light means the one you really are. This, in Bhāratīya culture too, is dvaita: that is one thing, I am another. There is a difference called this and that. How much difference there is between this and that! This means here, that means far; far from what? Near to what? So long as he does not recognise … principle, a man says only this and that. When we inquire near to what and far from what, this is near to the senses, that is far from the senses.
