This photo says that worship can be done from anywhere without a fixed proper place. However we should keep a fixed place for worship neat and clean.
I had captured this photo somedays ago randomly when I crossing this place, I saw a Sack Hawker was busy in worship with the help of Priest witnessing by Fire in his Sack Godown.
You can see lots of Sacks in background and only sitting palace is vacant and that place has been utilised for worship.
That's great actually.
