Mr Jain runs a tea shop that he claims is more than 150 years old.
This shop is tucked away in a corner on the main thoroughfare of Chandni Chowk, Delhi.
He also dispenses medicines , free of cost, to diabetics. They are home remedies actually.
When he is a bit free from his business, he regales his customers with stories of the past of Delhi.
You can even note down his telephone number on the photograph.
He is a good soul.When I visited him last month, he answered my questions with supreme patience.
Mr. Jain told me that there was a canal that ran right in the middle of the main avenue of Chandni Chowk.And yes, there were trams too for transport till the beginning of the 20th century.
Mr. Jain belongs to one of the most affluent communities of India and is an adherent to Jainism. This is a sect that is contemporary to Buddhism.
Delhi is home to a lot of Jains and Dariyaganj suburb has a good number of Jain residents.
Jains have lived in Delhi for more than 1000 years and are the greatest champions of non violence, also known as ahimsa.
It is people like Mr. Jain that have maintained the ancient character of Delhi.
