Amitabh visits Sabarmati Ashram, tries his hand at charkha

The shots required the 67-year-old actor to walk in the region but he decided to walk bare foot in the ashram.

"I removed my shoes by the road and walked about barefoot, even though all others do not. It is not required that they do so but I could not somehow make myself to not go barefoot. The sanctity and the purity of the premises just prompted me to do it," Bachchan wrote on his blog.

"I sat with the lone figure of an inmate of the trust that runs the ashram, as he spun the 'charkha' and produced the fibre for 'Khadi'. I tried my hand at it. Its simple yet intricate procedure in weaving the thread and the extreme joy of having been so close to that most identifiable element of the Mahatma, overpowering all other thoughts," he wrote.

Later in the evening, the veteran actor was presented the first audio visual films of the tourism campaign and was informed about the origin of charkha (spinning wheel).

"A young girl who lived in a far off village near by, Ganga Ba, had lost her husband at an early age and in the 19th century initiated the process of educating women in her region - an unheard of phenomena of those times - and also building the first 'charkha' or spinning wheel which when she was visited by Gandhi presented it to him. Thus began the entire revolution of the wheel and khadi. Fascinating tales!," Bachchan wrote.
