+title: Sikh Langar Free Kitchen
+description: >-
+  A Sikh practice of preparing and serving a free communal meal to all who
+  come, regardless of caste, religion, or status, and eating it together
+  seated on the same level. Originating with Guru Nanak in the 15th century
+  and central to every gurdwara.

+steps:
+  - headline: Prepare the meal
+    description: >-
+      Volunteers (sevadars) prepare a simple vegetarian meal — roti, dal,
+      vegetables — in the gurdwara kitchen. All food is vegetarian so all
+      can eat.
+  - headline: Serve to all
+    description: >-
+      Servers offer the meal to each person who comes, regardless of
+      background, caste, or faith. No one is turned away.
+  - headline: Sit on the same level
+    description: >-
+      All eat together seated on the floor in rows, at the same level. The
+      equality of the seating is the point — no one sits above another.
+  - headline: Clean together
+    description: >-
+      Volunteers and guests clean the hall, wash dishes, and restore the
+      space. Seva (voluntary service) continues through cleanup.
+  - headline: Renew the practice
+    description: >-
+      Langar is prepared daily in active gurdwaras; the practice renews
+      itself each day, funded by the sangat (congregation) and served by
+      sevadars.
+outcome: >-
+  All who come are fed equally, and the equality of shared food embodies
+  the Sikh principle that all are equal before the Divine.
+practice: >-
+  The same-level seating is the practice — not just the free food. If
+  seating is reintroduced hierarchically, the langar is diminished.
+  Vegetarian food ensures all can share.
