but das will try to tell why that part which is included is included and why is it not anti Gurmat(Das also bleives that it is not wriitan by Guru but does belive that there is a chance of Guru getting a part of Raagmala writtan by other and including in Guru Granth Sahib like the writing of Bhagats or Sufis).
