Sikhs make an offering of money or food for the gurdwara's kitchen, which is known as the langar.

Sewa is an important part of worship. Sikhs fulfil this duty when they help in the langar or look after the gurdwara, study the Guru Granth Sahib and teach it to others and give money or other help to people in need.

This is why the langar welcomes anyone regardless of religion or background, offers free meals to visitors and some gurdwaras also provide beds for the homeless.
