Kandar Devta, Someswar Devta, Naag Devta these are all local gods because they are accepted and worshipped by local people. As long as you worship them, they will help you. In Gita (Bhagavad Gita) it is said :’To us who accept and worship,he only will help us…’Now people believe less and lose faith in gods, they worship doctors. Gods get angry as they don’t get celebrations and offerings. These gods will not help you.Therefore today people are not getting any benefit. If people don’t show feeling and respect for the god the god becomes less effective. This means that as long as we have repect for the god,things will go smoothly, but the moment we become careless toward the god, he stops helping us.
