Harivansh Rai, who is credited with works like "Madhushala" and "Agneepath", died Jan 18, 2003.
"It is the death anniversary of my Father. When you think of those moments it sends shivers, apprehensions, prayer and remembrance to the one departed, especially when it happens to be your own Father," the 72-year-old posted on his official blog srbachchan.tumblr.com Sunday.
"I shall be in prayer with him in his surroundings... for whatever little that we can do for him... it is after all the day of his passing. My Father... my father... lost today but in my thoughts and mind continuously... where do they go, and where are they that seek indifference to their problems."
"Many wonder if they reached the doors of heaven, of meeting that phantom like'old man' with rather large beard and a guffaw at his disposal... reverential and obedient and filled with pardon to be sought from the one that sacrificed his," he added.
Meanwhile, Big B, currently busy promoting his forthcoming film "Shamitabh", has cut his finger.
"Umff !! A crucible carrying my medication slipped out and smashed on the ground ! Glass all over ! Swept it aside ... finger cut," he tweeted.
"The kite finger cut had just healed when there was fresh blood all over ... sounds gruesome no??? Ok no more...," he added.
