Anthropologist Hari Mohan writes that after the rituals are over, the karam story is narrated to boys and girls.
The story behind the festival, according to Mohan, is this:[17] Once upon a time there were seven brothers who labored hard at agriculture work.
In the evening they returned home and found that their wives were dancing and singing near a branch of the karam tree in the court yard.
The karam deity was insulted; as a result, the economic condition of their family continued to deteriorate and they were brought to the point of starvation.
One day, they were so engrossed in dance and song that the brothers' morning meal was not carried to the field by the wives.
Thereafter he returned home and called his brothers and told them that because they insulted Karam Devta, they fell on evil days.
As it was the day of the Karam festival, all the women were engrossed with dancing and the men with playing the drums, so no one came to receive him.
After spending the whole night with dance and songs, the people uproot the branches and carry them to nearby rivers or rivulets for immersion.
