Yes, knowledge of different schools og thought in india and even in islam is very helpful for Gurbani. Good taksaals/vidhaalye and steeks/tikakaar will teach you the background of every shabad. As the gurujis had many conversations myriads of people from all schools. And some of gurbani is those responses, background is very important.
Even knowing the stories of Rama etc.
Don't be suprised if alot of videos that exposed these people and things go missing. The so called protecting kids and hate speech is a sham its actually denying free speech and free expression of thought. Cos alot of mild videos with alternative views and thoughts are taken down and channels closed for no reason. There are some nasty racist and pedofiles that deserved their channels closed but those warning people about stuff and videos even featuring crimes by governments and groups they got taken down too. Yet they were important in highlighting the crimes of these people so people could see the truth about what they got up to.
Here is my list of current problems we face as a kaum.
Traveling around giving aid / langar to non-sikhs. This thought was put into Sikh psyche as a strategy to destroy Sikhs from within by the enemy who wanted to move Sikhs away from position of strength to weakness. Guru ka langar never went around the world helping non-sikhs like this. Guru Ka langar was based on giving langar to the local sangat community. However was the non-sikh poor masses who came to the Sikhs and gurdwara's to get langar and get parchar to convert to Sikhi that made non-sikhs want to be a Sikh. This current innovation which has been created and run by idiots and is wasting sangats money giving langar away for free with no benefits for the kaum. The biggest gift a Sikh can give to a non-sikh is parchar because by that parchar the Sikh too will have to reform their character to live by what they preach.
Not having well armed sewadaar guards of Gurdwara's. Safety and security of guru's house and his congregation should be paramount yet what do we see today? any afghan ahmed abdali, isis salafi muhammad musin, mughal aurangzeb can walk in and kill without any hindrance like we seen recently. What is the fall out? Sikhs will stop coming to gurdwara's and thus gurdwara commitee's lose income and gurdwara shuts down eventually. The non-muslim hating conquest loving isis type jihadi mullah nutjob wins as sikhi is seen as weak and finished eventually because gurdwara's are no longer safe spaces for people wanting to worship and congregate.
Sikhs of sarbat da bhulla mindset. Well meaning humanitarian liberal Sikhs but very gullible very politically and religiously naive not understand the full context of meaning of sarabat da bhalla and when to apply it. perhaps most of them have a sort of stockholm sydromme imprisoned by cultures and ideologies that are against Sikh interests and prevent their own community to survive.
Fake Sikh puppet leaders. They are only in it for their own power, fame/popularity contest or financial gain (eg recent akal takht jathedhars, sgpc leaders, DT harnaam singh, Badal dal, congressi captain amrinder singh, etc). We need to support leaders who openly fight for the interests of Sikhs without being shy about it.
Not having our own sovereign state nation. To conduct our own economic, military, religious and political affairs is the very reason we have so many problems. But its not necessary for the community to survive and thrive if other problems are dealt with.
Inter-faith marriages and lack of promotion of inter-caste or inter-race Sikh marriages. Sikhs should activity promote inter-caste marriages within punjabis at the very least and help promote those non-sikhs to convert to Sikhi to marry someone within the faith.
The tell-tale sign of an appointed gatekeeper of public discourse. Guiding the narrative and traffic of discussion away from "dangerous" areas that might prove to be troublesome for those at the very top. Someone like that gets to that position usually through attendance and membership of lodges...
You can tell we're under lockdown. The mind goes to strange places when all the work of the day is done, lmao.
