Shri Guru Singh Sabha Gurdwara in Ghaziabad has come forward to help patients with low oxygen levels and save their lives through an initiative called 'Oxygen Langar'. Just like any other langar (community free kitchens) organized by the Sikh community, 'Oxygen Langar' is also based on the philosophy of 'Seva' or selfless service. The Gurdwara has created a facility in its premises where patients can simply go and utilise the oxygen available for free till their oxygen levels normalise.
