। ॥ २७५ ॥
In plain words
Who is the ātman? And who, then, is the non-self? What is the mark that tells the two apart? And how does it come about that the qualities of the non-self are laid over the ātman?
Close to the Sanskrit
Who is the Self? And who is the non-Self? And what indeed is the defining mark of these two? How is the superimposition of the attributes of the non-Self made upon the Self?
