Sat Sri Akaal ji, Was just talking to a friend online and we were talking about listening to keertan at home and he said that he wanted me to listen to one... cut a long story short I said I couldn't because there were others down here that had uncovered heads, and he said that he knows people that do not cover when listening to keertan at home? I have always done this, even when reading any Gurubani online... is it really necessary or not [personally I say yes]... but why do some say its not? Just a short question... thanks!!
