Any Hare Khrishna temple will do the same, but I'd lay odds that if you approach anyone in any type of temple/church and tell them you're hungry you'd get a meal.
You do not get this in the Masjid (Mosque) apart from few special occasions as people should come to the place of worship entirely because they want to worship (whoever )they believe but should not be attracted due to free food.
However in sub-continent you go to shrines of any famous saints and you would get food 24/7 and even in Sikh religion I think it came from there.
The sikh temple dont advertise free food; it's purely an observation that I find exceptionally charitable for their followers, ensuring none of them go hungry.
Going into the shelter of a temple for a meal (whether destitute or not) is not the same as a truck arriving to pass out free sandwiches to the homeless. In the Temple you can even sleep on the floor (in shelter).
A church/temple/mosque is just the meeting place for those to practise their faith.....it's not the religion itself.
Am not preaching am just impressed with the generosity of the temple which shows up the other places of worship.
FRom what I understand of Sikhism is that they'll feed anyone who needs to be fed, regardless of faith.
The remarkable thing about Sikhism (in India) is that people will be fed without reference to caste, or wealth.
Quite a radical thing in the Sub-Continent.
From what I have experienced, they will. There is no religious pressure though there are readings of their holy book which can be heard. You can also visit at the readings (to pray) and leave a donation but without pressure.
I have heard that Buddhists do the same but though I have been to their temples abroad I never saw any feeding for visitors, paid or unpaid.
Why not try your local temple and report back here......am interested?
