The Langar is the free kitchen which is open to all. It was founded by Baba Nanak. The philosophy behind it was a radical departure from the prevailing norms of Indian society at the time. Ridden by caste hierarchies and the restrictive religiosity of the ruling class, the Langar was a place where peasent and king, man and woman, high and low, saint and sinner could sit as equals and eat together. In India, dietary rules have always played a restrictive part in everyday life. Such a practical expression of equality, embedded in the very heart of the place of worship, was unprecedented. This ethos remains to this day, and is perhaps the most visible and obvious manifestation of Seva that we encounter in our lives in modern times.
