Bujharatan are riddles, asked by adults to children and by children to each other, usually in a fixed rhyming form with a set opening.
Their subjects are the objects of a Punjabi house: the chakki, the charkha, the well, the lamp, the sieve, the buffalo, the moon. They are a description of a material world that has largely gone, preserved in a form designed to be memorable.
A riddle about a Persian wheel is unanswerable by a child who has never seen one, which means a large part of the repertoire has become inert within one generation.
The same is true of the baat, the folk tale told at night, and of the lori, the lullaby.
This material was collected in Punjabi in the twentieth century by folklorists including Devinder Satyarthi and Sohinder Singh Bedi, and the collections are out of print and hard to find.
A village grandmother's repertoire of riddles, tales, songs and proverbs is a body of literature. Nobody has recorded a complete one.
The bujharat is put as a short verse and the answer is an everyday object: the well, the lamp, the grinding stone, the shadow, the mirror.
They were asked at night, in company, as a competition between children and adults, and the good ones survive because they are hard rather than because anybody wrote them down.
Collections exist in Punjabi from the colonial period and from the folklore departments. They are out of print and the practice has largely stopped.
