What cannot be comprehended with the mind, but because of which the mind can comprehend and think. That is Brahman and not what people worship here.
What cannot be seen with the eyes, but because of which the eyes can see. That is Brahman and not what people worship here.

What one cannot breathe in with breath but because of which one can breathe. That is Brahman and not what people worship here.
