The traditional scholars claim that all the works in "Dasam Granth" were composed by the Guru himself, on the basis of Bhai Mani Singh's letter. But the veracity of the letter has been examined by scholars and found to be unreliable. An example of varying style can be seen in the sections 'Chandi Charitar' and 'Bhagauti ki War' . Some others dispute the claim of the authorship, saying that some of the compositions included in "Dasam Granth" such as "Charitropakhyan" are "out of tune" with other Sikh scriptures, and must have been composed by other poets. The names of poets Raam, Shyam and Kaal appear repeatedly in the granth. References to Kavi Shyam can be seen in Mahan Kosh of Bhai Kahan Singh Nabha, under the entry 'Bawanja Kavi' and also in Kavi Santokh Singh's magnum opus Suraj Prakash Granth.
