Abhishek Bachchan says his father Amitabh's dialogue "Mard ko dard nahi hota" from the movie "Mard" couldn't be more relevant than now, when the ailing megastar is keeping his spirits high despite battling serious health problems.

"Morning spent with pa at hospital, then at NASCOMM in the afternoon. Back to hospital where, despite his pain, SrBachchan is cracking jokes. Guess he said it true in his film 'mard ko dard nahin hota!' Legend," Abhishek posted on his Twitter page Thursday night.

Amitabh is currently admitted to the Seven Hills Hospital, where he underwent two surgeries Saturday. 

The 69-year-old is still in pain. Though the Bachchan family and hospital authorities are tightlipped about the further procedures, sources have informed IANS that Big B is likely to go under the knife again Friday.

Amitabh indicated through his Thursday night blog post that more doctors were called in for consultation on his condition, but for now, he has chosen to keep details of his condition to himself. However, he is finding solace in the company of his wife, Jaya, children -- Abhishek and Shweta, and friends.

"Wonderful feeling to see old friends drop by the hospital... we may not meet at work, but when either in trouble... they are there... To those who pray and wish recovery for me, god bless and thank you for thinking of me so fervently... Shweta's wedding anniversary today, but she stayed back to be by my side... daughters are the best... Abhishek returns from Jaipur shoot to be with us...greatest joy for parents is the love of their children...all else comes afterwards," tweeted Amitabh.
