Sarbloh Granth literally means "the Granth or Scripture of all-steel (or iron)". However, many scholars and researchers question the authenticity of the Granth and its credibility remains in doubt.
According to Pandit Tara Singh Narotam, a nineteenth century Sikh scholar and researcher, the Sarbloh Granth is the work of Bhai Sukha Singh, a granthi (priest) at Takht Sri Patna Sahib. Bhai Sukha Singh, however claimed that he had acquired its manuscript from an Udasi recluse living in a forest near Jagannath Puri (Orissa).
The Akali Nihang tradition who make use of the Granth holds that whereas the Guru Granth Sahib is the embodiment of "Shaant Ras" (essence of peace), the Dasam Granth and the Sarbloh Granth are the embodiments of "Bir Ras" (essence of war). They believe that the difference between the Dasam Granth and the Sarbloh Granth is that although "Bir Ras" is born in the Dasam Granth, it is in the Sarbloh Granth where the individual warrior achieves an everlasting, final and complete lethal cutting edge advantage in this sphere of "Bir Ras". This Nihang belief is not accepted by the majority of the rest of the Sikh community.----> .....More
