As part of of Food Tour of Delhi we visited the Gurudwara Bangla Sahib. This temple is one of the most prominent Sikh temples in Delhi, India. Earlier in the food tour I asked our guide Jaidev about the people we saw living in the street. I was concerned that they were so thin. Some adults and children looked like they were literally starving! Our guide explained that no one leaving near a temple should starve as they can be fed by the temple kitchen.
Jaidev explained a lot of the temples practise a policy of Langar. This term means the temple has a kitchen staffed by volunteers that will provide a meal. There is no payment for food and all visitors to the temple can partake, regardless of religious beliefs.
