The following is this Daas' personal observation. Some Gursikhs may not agree with it. It is not directed towards anyone in particular.
At AKJ Samagams, Gursikhs try their utmost to maintain Maryada in Kirtan Seva, Langar Seva etc. i.e., allowing only those Gursikhs to do Seva who are in good standing as far as their Jeevan and Rehat is concerned.
The same Gursikhs, when holding Samagams at their homes, do not mind if a Bibi without Keski does Kirtan. They do not mind if Degh/Langar is cooked in non sarbloh utensils or any Gursikh wearing pant/pajama sits at Tabiya of Guru Sahib.
My question to them : When you are having Samagam at your home, is it in some other Guru's presence or is it the same Guru who was present at any AKJ Samagam?
