I am not a big scholar on this subject. But some parts were still not written by Guruji and that is enough, when you compare it to Adi Sri Guru Granth Sahib.
The sant samaj is cutting at the roots of Sikhism, and they don't even have an authority in any Sikh scripture. Most preach kachi bani. Many of them are bad as the most Jathedars.
The most pious man i have seen in my life was Bhagat Puran Singh. He was a thousand times better than modern sants, yet he called himself Bhagat and not Brahmgyani Sant Baba.
i agreeeeeeeeeeeeeeee
