Ratula Bandyopadhyay's life can be summed up as:
"Sorrow drips into your heart through a pinhole/
Just like a faucet that leaks and there is comfort in the sound/
But while you debate half empty or half full/
It slowly rises/
Your love is gonna drown."
While the words and language used may vary, the goal of gaslighting is to undermine the target by portraying her as unreasonable, unreliable and inherently defective in mind as well as character/morality.
