All your views are not your own views, they are very much dependant on the understanding of the others.
If we are ready to look into what Principal Harbhajan Singh says then why not examine others like Giani Ditt Singh ji.
Why should we should we consider Dr. Jaggi's opinion............... just because he says that the letter sent by Bhai Mani Singh ji is fake primarliy because it was a written with a Nib in a vijogatamak style(words separated), this claim has been refuted by the Mool-Mantra signature of different Guru Sahibaan.
Bhai Ditt Singh is a known scholar in the panth, who not only helped in the establishment of Singh Sabhas, he also fought the Bippars (Pamma Prabodh), the muslim Pir worshippers( Gugga Gapora from Sultan Puara), who also took the fake sikhs to task ( Nakli sikh prabodh) and he also clarified the doubts of those who based on chandi-ki-vaar and bachitter natak wanted to prove that Guru Gobind Singh was a Devi Bhagat.
A very simple reason that I request Tejwant ji to start a reading of "Durga Prabodh" as it has poetry and is explanation also by Giani ji himself, so we have no doubt on its interpretation.
Apart from this I personally fell that being too much logic oriented; we start rejecting all that which doesnot come into our logical understanding.
