Like most grandfathers, Big B is also full of wisdom, great life advice and inspiring words that he wants to share with his grandchildren.
Perhaps it was his upcoming movie Pink, a social thriller reflecting on gender disparity that motivated him to pen an open letter to his granddaughters, Navya Naveli, 18, and Aaradhya, 4, about the struggles of being a woman and the boxes the world tries to place you in.
Here's the letter that the 73-year-old actor wrote:
"My very dearest Navya & Aaradhya,
You both carry a very valuable legacy on your tender shoulders – Aaradhya, the legacy of your great grandfather, Dr Harivansh Rai Bachchan and Navya, the legacy of your great grandfather, Shri H P Nanda.
Both your great grandfathers gave your present surnames celebrated fame, dignity and recognition!
Both of you maybe a Nanda or a Bachchan, but you are also girls, women! And because you are women, people will force their thinking, their boundaries on you.
