Following are the 11 Bhats who’s baani is in Siri Guru Granth Sahib jee. These Bhats travelled for one year throughout the Indian subcontinent but could not find anyone who could quench their spiritual thirst and in the end they came to the Darbar of Siri Guru Arjun Dev jee. They became Sikhs of Guru and then Guru jee enabled them to pronounce Dhur kee Baani:
Kal Sahaar
Jaalap
Keerat
Bhikha
Sal
Bhal
Nal
Gayand
Mathura
Bal
Harbans
Apart from them Vaar called Ramkali kee Vaar and Tikke kee Vaar, that was read by Hazoori Raagis of Guru Sahib. Their names are:
Rai Balwand
Satta Doom
Finally a baani called Ramkali Sadd was pronounced by Sunder jee, the grandson of Siri Guru Amardas jee.
In total, the contributers of baani of Siri Guru Granth Sahib jee are as follows:
6 Guru Sahibaan
15 Bhagats of Guru Nanak Dev jee
11 Bhatts, Sikhs of Siri Guru Arjun Dev jee
2 Hazoori Raagis – Sikhs of Guru Arjun Dev jee
1 Grandson and Sikh of of Siri Guru Amardas jee
Total contributers are 6 + 15 + 11 + 2 + 1 = 35
Some Gursikhs believe that there is baani of Bhai Mardana jee too in Gurbani but this is not true. Those saloks with heading Salok Mardana (Mahala) 1 are saloks written by Siri Guru Nanak Dev jee but probably addressed to Bhai Mardana jee.
One thing I would like to add is that in many old saroops there is one salok under the heading Mahalla 10, within Saloks of Siri Guru Tegh Bahadur Sahib jee. I personally am sometimes inclined to believe that this indeed is the baani of Siri Guru Gobind Singh jee Maharaaj but present printed Birs of Siri Guru Granth Sahib jee don’t contain this heading of Mahalla 10. If we were to assume that this indeed is the baani of Siri Guru Dasmesh jee, then the total contributors of Gurbani would rise to 36.
Daas,
