Navya Naveli is the daughter of the 72-year-old actor's first born Shweta and her Delhi-based businessman husband Nikhil Nanda.
"Look what took its place the entire day... The life to witness the gift of a grand daughter, of her accomplishments, of her talents... That is more than what many wish and possess."
"And yes the inner joy of admiration for Navya as she surprises us all with her hidden talent... The music and the keys of the piano, untrained, unread. Just performing with the mind and what has remained with her somewhere, astonishing," Bachchan posted on his blog.
The actor also shared several pictures in which he is seen sitting alongside Navya Naveli, who is playing the piano at her grandfather's home.
"That piano is the little space in my small little room.. a space that I occupy on occasion.. spend time with keys black and white.. life is made of just these two they say.. but there are so many other colours too.. and they bring joy and a brightness in us as well," Bachchan wrote.
