AADI GRANTH AND DASAM GRANTH
Guru Gobind Singh ji, before passing away, gave Guruship to Guru Granth Saheb, also called Aadi Granth" (Aadi means the first).
Guru Gobind Singh ji included the bani (writings) of the 9th Guru, Guru Teg Bahadur ji, in Guru Granth Saheb, which was originally compiled by Guru Arjan dev ji (the 5th guru).
None of Guru Gobind Singh ji's writings are included in Guru Granth Saheb. His bani (writings) are included in a separate Granth called Dasam Granth (Dasam means tenth).
Two of the five banis included in our Nitnem (the daily prayers) are written by Guru Gobind Singh Ji. These are Jaap Saheb and ten Saweyeas. Chopaee Saheb, which is included in Rehras Saheb, is also written by Guru Gobind Singh ji.
