Prime Minister Narendra Modi in his biggest interview this election season with India TV's Chairman and Editor-in-Chief Rajat Sharma spoke on BJP's 400-plus seats target, Pakistan, revocation of Article 370, his government's action against corrupt politicians, among others issues.
The rich and powerful keep trying to tell us they are sent by god or authorized by god to rule on us. They have done that since the dawn of civilization. It's our duty to remind them they are not, and that they are earthly and mortals.
Yes, Hinduism is polytheistic. There is a hierarchy of the gods to a certain extent and depending on your sect the most important god can vary a little.
Though I suspect that this is just a translation issue. The interview is in Hindi( I think). I am guessing that the person who wrote the article was writing it for a American/British audience. They probably just decided to use the word god because it was easier and conveyed the messages better the intended audience.
