Its good that sangat are getting Bir Raas from watching this video.
My two cents:
Rather than just showing videos about it (which is important aswell), it is important that we are all on another level with our Bani as that is most important. Take Amrit if you havent already, wear Bana 24/7 as this is an important Rehat of Guroo Sahib aswell, and become Shasterdhaari.
Also its also important not to tie a Dastaar like the guy in the video, look how easily it came off, no Keski or anything. Dhumalla is always the best for protection and firmness.
