Hello Everyone, I am new to the forum, my name is Sohini Roy. I am a Bengali, and to answer your question - it is called "Ulu Dhwani", usually a ritual done in weddings and Puja to ward off evil !!
I am hooked to the show because it is written in lines with Bengali novels by Sarat Chandra Chattopadhay or Bankim Chandra.
The heroes in these novels are flawed, sometimes weak, at other times vengeful but relatable humans so their actions look unjustified at times but sense is usually shrouded by misunderstandings - they love wholeheartedly but societal pressure and circumstances may force the love to take a backseat for a while !
And the heroines overwhelmingly patient and sincere in love, extremely giving and sacrificing in love!
It is the kind of love where they could give their lives for each other with out uttering a ouch ! Selfless and Giving !! The kind of love where you never need to utter a "I love you" or need physical intimacy ! It is a love way above, it needs no declarations, actions always speak louder
