From time" immemorial"...elements have been trying so very hard to "divide and separate" the Gurus...sometimes via their "birth"..bedis and bhallas...and sodhis - (Bachitar Natak)..sometimes via ..arm chair philosphies/theories...like..
Sixth Guru Hargobind wore two swords and took the Path of Militancy, turning the "peaceful" rleigion into a WAR ZONE ....abandoned the simple clothes and began to wear Royal clothes, began to ride horses instead of WALKING ABOUT on foot...kept soldiers, bore arms, made Takhats to sit on etc etc.. (Gurbilas Patshai Chhevin)
Then the next 3 Gurus are sort of kept in "low profile" mode even though Guru Har rai ji kept an armed Guard of 1000 of the best soldiers, Guru HarKishan ji even as a child REFUSED to see the Mughal Emperor and ignored his call..and the Guru teg bahadur Ji gave his head...and the DIVIDE separate policy again came into force with even greater strength...Guru Gobind Singh was BUSY doing Tapaiysiyah ( It doesnt matter that he was supposedly a Dusht Daman in a previous LIFE-FORM (NOT HUMAN), but the PLACE is right here on EARTH !!....when He was called upon by the Supreme to GO DOWN ?? from Hemkunt to HEMKUNT ?? and begin a BRAND NEW PANTH...( when Guru nanak Ji had already begun a BRAND NEW PANTH called the NIRMAL PANTH and which PANTH was nurtured and grown by the Nine Gurus following Him...which PANTH already had a Central Place called Akal Takhat-Harmandar Sahib, several other centers of propogation, the AAD GRANTH SGGS all ready)....so the Supreme is saying that NOBODY HE SENT DOWN EARLIER had a GOOD WORD TO SAY ABOUT ME !! each only talked about HIMSELF..IF this statement is not about Completley IGNORING the 1429 page HUGE TOME AAD GRANTH/SGGS in which EACH WORD is about ONLY the SUPREME and nothing else..and the words/actions of the 9 Guru Sahibs over the past 200++ years..then whats it about ??? and that ONLY DUSHTDAMAN going down form his Hemkunt mountain..can do the JOB (which means Guru nanak ji and his 9 following GURUS FAILED to do what they were sent down for ??).
And then the plot thickens...the Last Guru has not only a New GAME PLAN, is a former Dusht daman (not Human ) turned HUMAN, He is also a DEVI Worshipper, has his own "Granth"..etc etc.. The Last Scene of this ACT of the Strange Drama (Bachitar Natak ) is being actively played out NOW...the DG and resulting controversies DIVIDING the NIRMAL PANTH/GURU KHALSA PANTH are a continuation of this scenario from Gurbilas Patshai chhevin and so on...Several Hukmnamahs which are based on hearsay, fake writers who wrote and added vaars to established and respected writers like Bhai gurdass ji,..etc etc are all spokes of this nefarious wheel of division... We have always had Sikhs who...."Oh i am a sikh only of Guru nanak ji..I love wearing a TOPI..becasue Guru nanak ji wore one....OH I am a sikh only of Guru ramdass Ji..Ilove amrtisaree daall..oh I am Sikh only of the first 9 Gurus..I dont like keeping LONG HAIR...etc etc..BUT what these dont get is the 10 Gurus are ONE, the SGGS is ONE, gurbani is ONE, Akal Purakh is ONE..our vichaar is ONE..we worship ONE..and always be ONE...we just cannot pick and choose what we want...its either ONE or NOTHING.
TRUTH is that the 10 Gurus are ONE JYOT, they preached the EXACT SAME MESSAGE thats now in the SGGS and thats why SGGS is called the JYOT of all 10 GURUS even IF 3 didnt write a single word in it - they still get the CONNECTION/in the LOOP... because they followed it to the Letter and in Spirit - Shabad Guru all the way form 1469-1708.
