BHforce do you know who the giani talking in the Video is? He is Giani Gurvinder Singh Ji Nangli Wale, a fully fledged Nihang Singh respected by all vidhvans of Budha Dal and Tarna Dal. they themselves run a Gurmat Vidhyala under Panth Akali Tarna Dal Baba Bakala. The recent Budha Dal Sarabloh Granth Sahib Paath Bodh was conducted by Giani Gurvinder Singh Ji, Giani Ji is a great vidhvaan who has studied aadh, dasam, sarabloh, vedant, Sanskrit and Farsi in depth. The old Budha Dal Gutka has many typo mistakes as it was printed by Chattar Jeevan Singh Amritsar rather than Budha Dal directly. You can ask many Budha Dal Singhs they recite the extra line in Braham kavach as Giani Ji has stated.
The rope is strategic in many ways.
Out in the wild and need to make weapons, you may need rope.
Need to make a little makeshift roof, you need rope.
Need to tie anything together for the purpose of surviving, you will always need rope.
Dori also saves the issue of gatra breaking, etc
Guru Nanak Dev Ji's Parkash is disputed between 3 Dates
Friday, Katak Sudi 15 Pooranmashi, 1526 Bikrami (Lunar)
Saturday, Vaisakh Sudi 3, 1526 Bikrami (Lunar) (Not Pooranmashi)
Monday, 1 Vaisakh, 1526 Bikrami (Solar Date) (Pooranmashi)
There is debate on this issue, I recommend reading the document mentioned in the OP.
Also PLS, Benti for everyone, when referring to Gurpuabs, pls use Bikrami or Mool Nanakshahi (Which are basically Bikrami dates) dates, don't use English dates as they are not accurate as the original.
We need more people to start using Desi Months and days, Barah Maha Parro!
Serious question though, how would one use a Dori Kirpan practically? Like how would it be used?
I think thats why some people say its just for show because maybe you can't use it well? I wouldn't know.
