Origin

The janamsakhi stories likely began through family and friends close to Guru Nanak, spreading to others. The earliest layer of what was to become the written tradition later was, according to McLeod, "authentic memories concerning actual incidents from the life of Nanak," in conjunction with the verses left by him in what would become the Adi Granth. The first janamsakhis were oral in nature and began spreading across the Punjab when news on Guru Nanak's exploits and fame started being passed around. They were first put to writing likely around the early 17th century. However, according to Pyar Singh the earliest dated extant janamsakhi manuscript is from 1588.
