Brilliant!!
Can you give me more information on this? This sounds fascinating.
I don't have the info on this, if there are researchers on this subject on this site, who know more about the muslim murids who were known as the Khulsa as opposed to the Khalsa which sikhs were called, the researchers could enlighten on the subject, unfortunately I know very little.
I heard this from Nihang Niddar Singh, so someone who knows him or practises Shastar Vidiya can find out more from him, but there are other researchers on the net who know a lot as well.
Another thing I know is that as opposed to Shaheedi Degh, there is also mureedi degh, which is sukha without being sweetned done in honour of the muslmaan mureed shaheeds.
