The event you are referring to is very sacred and awaited by Hindus. In Bengal, there is no regard for race and religion, in fact the people are very tolerant. When Hindus worship, those who follow other religions will be tolerant and give generosity. Almost every country has a different ethnicity and religion, but it must be tolerant and not interfere with the worship of others. It's nice when I see people from different religions, but they participate in the event regardless of one's religion.
