The 69-year-old, in a white kurta pyajama, Sunday addressed the well-wishers gathered outside his home Jalsa.
"God bless the well wishers. God bless them for their permanence in my life. God bless their consistency, their love and enthusiasm.
I am indebted for life. It is a debt I shall never be able to repay; the one burden that shall remain with me unattended. One burden that shall make me happy," Amitabh posted on his blog bigb.bigadda.com.
The megastar was operated upon last month and is currently recuperating at his home here.
He is advised complete rest by his doctors with restricted movement and diet.
