A N Murthy Rao's book - Devaru. Presented by "Kannada Tota" Podcasting channel. This is chapter 4 of his book titled: ದೇವರು ಒಬ್ಬನೇ ಎಂಬ ಕಲ್ಪನೆ where the author raises logical questions on the concept of "God is One". He contends to the explanation of DVG in his "Devaru" book where he tags God with "Karmadhyaksha" and "Sakshi" titles per Upanishad shloka (shwetashvataropanishad) and AN Murthy Rao goes to dissect those titles to show how they both are contradictory in nature and cannot exist together as well as, how both are just useless and jobless titles / roles.
