Janam Sakhi Bhai Bala Ji Wali
There are many other Janamsakhi PDFs present, but the most famous among them is Janam Sakhi by Bhai Bala Ji based on the life journey of Guru Nanak Sahib in detail. Prediction of its written year is highly debatable, and most modern Historians consider it was written very late even after the ascension of Guru Gobind Singh Ji.
