Duni Chand was a wealthy man of Lahore who flew seven flags over his house, one for each lakh of rupees he owned, and who invited Guru Nanak Dev Ji to a feast for his ancestors.
The account says the Guru gave him a needle and asked him to return it in the next world. Duni Chand said nothing could be carried there. He was asked why he was accumulating so much then.
In the same visit the Guru is said to have asked what use the food offered to dead ancestors was, when the ancestors could not eat it, and to have pointed out that a starving man was outside.
The needle story is told to children across Punjab and is one of the very small number of Sikh stories that has spread outside the tradition entirely.
Gurdwara Janam Asthan Duni Chand and other sites at Lahore are associated with the visit.
The account is of a rich man at Lahore who flew a flag at his house for each lakh he had made, and who was given a needle to keep and hand back in the next world.
He said he could not carry it. The answer is the whole point of the story and it is delivered in one sentence.
He appears in the janamsakhis as a real Lahore merchant, and the story is among the small set that every Punjabi child is told, in every version of Punjabi schooling.
