For us both baba nanak and Pir Guru Gobind Singh ji are important.Guru Gobind Singh ji and Pir Buddhu Shah gave their lives to save hindus and shias both who were being exterminated by Aurangzeb.The first persons to come to to aid Guru Gobind Singh ji was Pir Buddhu Shah ji and when Pir Buddhu Shah ji with 700 of his followers when the hill rajas alongside the mughals attacked guru gobind singh ji and ultimately Pir buddhu ji was killed by Emperor Bahadur shah,Guru gobind singh ji sent Banda Bahadur ji to kill the Governer of Sirhind who was responsible for killing the Guru's sons and Pir Buddhu Shah ji.
Same can be said for brahminism and its civil wars with buddhism which led to the varna system weakened India considered and opened it to islamic invasions,once a zen buddhist monk told me that what happened to india was divine punishment from higher forces for mass murdering and attempting to crush buddhist saints ,but then I asked what about the brutal mass murders of buddhists by muslim invaders in Afghanistan and the burning of nalanda, he said islamic world then suffered the death of more than 100 million in the hands of Tengri Buddhist Genghis khan and his son Hulagu Khan. ..Yes, I know about the mullah ulema and sunni pseudo sufi who instigated Aurangzeb to start conversion and genocide against Hindus and shias.Ultimately it is said that Guru ji put a curse on the Mughals and their descendants that they will be uprooted and destroyed and look at the descendants of Mughals today,they live in slums of Kolkata.
I have read up , and your statement that mercenaries have no religion spoke volumes to me . Saints have no religion and those who murder saints whether hindu,sufi,buddhist,christians face divine punishment to extremes....If Pir Buddhu shah ji was some mercenary then Guru Gobind ji would not have ordered Banda Bahadur ji to attack the Mughal Empire and bring the mughal murderers of Pir Buddhu ji to justice.But I guess you despise us for the actions of mullahs and their mad followers.Sufis and the mullahs are different.
Forget politics ,contemplate the name of the divine one in which ever name you know ...ultimately kings,politicans use religion for power.Saints use religion for enlightenment and to serve the meek and the weak of the world. And priests use religion as business.
I prefer to listen to saints.But you do not.
