This is the edited and annotated version of the earliest original text of "Janamsakhi". It has been prepared by comparing the three oldest manuscripts known as England Manuscript. It covers all the major incidents associated with Guru Nanak throughout his entire lifespan. What distinguished these editions from the earlier editions are the extensive footnotes about the variations in the three manuscripts and certain divine versus which do not occur in Guru Granth Sahib's text. Similarly, the spellings and the script have also been polished without altering the original text. The gaps have been filled to keep continuity of narration by taking the missing words and sentences from one or the other manuscript. This makes this edited version complete in all respects as well as a refined version.
