There has never been any doubt about the divine truth that GurBani is Sat. There has never been any doubt about the divine truth that GurBani is the Gyan Saroop of Dhan Dhan Paar Braham Pita Parmeshwar Ji. There has never been any doubt about the divine truth that GurBani has come from Akal Purakh. Therefore, there has never been any doubt about this divine truth that Dhan Dhan Shri Guru Granth Sahib Ji is the SatGuru since it came into existence with the blessings of Dhan Dhan Pancham Patshah Ji SatGur Arjun Dev Ji Maharaj.
