Ok, you tell me what to worship and give me concrete evidence of why I have to worship that. What is wrong with people worshipping milestones, rat, cows, donkeys etc. Do you feel that God exists only in temples or mosques or churches? Widows being burnt is only superstition - it is a social evil. You seem to be one who belong to the clan that shows practices of one community to be poor (howver miniscule that percentage might be) for the sake of conversion.
