Mother India
Tulsi -- the name is adopted from Harkishan Mehta's work, Jad Chetan -- is the heart of the serial.
Smriti Virani scaled heights, which perhaps only Arun Govil (Rama in Ramayana) had attained. Irani contested parliamentary elections from New Delhi and lost. But she retained her iconic status in the Indian house hold.
Her character, Tulsi, has become synonymous to greatness. She accepted her husband's illegitimate son, killed her own evil son, and fought against all odds to protect the Virani family.
