This is a very old Sikh monument located near Connaught Place in New Delhi.
When you enter in this temple, you have to take out your shoes and wear a special hat that they give you to cover your hair. Then, you are allowed to walk around the basins.
In this place, Sikh people are cooking and bringing food for the visitors of the temple; which is, according to me a very peaceful act.
This will be the good moment to learn more about the Sikh culture and their beliefs.
