The 72-year-old, who attended the "Swachata ki Paathshala" event here at a school, said it was an "enlightening" experience to spend time with the future of the country.
"A joy to be among them that shall one day be the future and run the country...They are free spirited, no inhibitions, no ego, no self consciousness, no fear and no ill will among them.
"They have truth, they have innocence and they do not hesitate to speak their minds without any hesitation...We need to learn so much from them," Amitabh posted on his blog.
"An exciting moment I would say for me and for all because when you shall see the programme you will realise that it was we that were the students and the students our teachers," he added.
The "Piku" star also shared a collage of photographs from the event on Twitter.
"A day spent with school children for 'Swachata ki Paathshala'...so enlightening and a learning for me," he captioned the image.
At an age when most of his contemporaries are taking rest, Big B is one busy man. Not only his hands are full with Bollywood projects, he has also collaborated with Star Plus for a unique project titled "Aaj Ki Raat Hai Zindagi".
