Jeevan Sakhiyan

The earliest biographical sources on Nanak’s life recognised today are the Janamsākhīs (life accounts) and the vārs (expounding verses) of the scribe Bhai Gurdas.
Gurdas, a purported scribe of the Gurū Granth Sahib, also wrote about Nanak’s life in his vārs. Although these too were compiled some time after Nanak’s time, they are less detailed than the Janamsākhīs. The Janamsākhīs recount in minute detail the circumstances of the birth of the guru.
