Re: Should we do this?
True. Just like Gyani ji said, if drinking the water from dust of visitors to Gurudwaras, teaches you humility, then it is OK.
I saw a weird practice in some Gurudwara in Ludhiana. There was dust from the shoes of people in Jodha Ghar which was kept in plastic pouches nicely tied by rubber band. And people were taking it away. I was left aghast and speechless. Dust of feet of saint eh? Such dust has to be EARNED by doing Sewa, not just taken off the counter!
