The Langar or free kitchen was started by the first Guru, Guru Nanak Dev ji. Mainly langar is pure vegetarian food served free in Gurudwaras. And is open for all. It is designed to uphold the principle of equality between all people of the world regardless of religion, caste, colour, creed, age, gender or social status. The tradition of Langar also expresses the ethics of sharing, community, inclusiveness and oneness of all humankind. It is the activity followed in Gurudwaras (Sikh holy place). Since langar is a part of the Gurudwara and the Sikh faith, everyone participates in langar. People sit in pangat(row or line) to share and enjoy the food, together. Males, Females and Children of all groups and of different castes, do sewa(voluntary help), to prepare and serve food. All the preparation, the cooking and the washing of utensils is done by sewadars (voluntary helpers). It is the sense of the universal equality of human being. Preparing, Serving and enjoying food by sitting together, is excellent effort by Sikh Gurus to make world understand that all humans are equal. Sikhs use langar to practice the Sikh doctrine of 'Service' known as 'Vand Chako'(share and eat). Anybody can visit Gurudwara and have meal regardless of his caste, creed, religion or gender.
