So I was on the ferry boat this morning, well actually I was leaving the ferry boat, and I noticed a guy in the waiting room praying. (The waiting room has glass walls) He was of a certain religion that prays to a city during the day (or a few times a day, I'm not sure) Anyways, I don't have any friends, or know anyone, who shares a similar belief as this guy and it always got me wondering. If they have to pray to this city how do they know where it is? Do they have a compass, or do they follow the sun, or is just a symbolic facing towards that holy city. Please fill me in? PS: I'd like to add that there is no disrespect intended, I'm just honestly curious.
