Sikhs, across the world, are celebrating the birthday of the first of the 10 Gurus, Guru Nanak. On this day, Gurudwaras are illuminated; teachings from Guru Granth Sahib read and processions, carried out. The followers of Guru Nanak, abiding by his teachings, donate clothes and distribute food to the needy on this day. Sikhs round the year do ‘sewa’ or service at the Gurudwara by volunteering for some or the other job like cooking or cleaning. However, on Gurupurab along with taking up these jobs, people also voluntarily serve milk to people. The followers of Guru Nanak set up ‘chabeel’ or stalls on the streets and offer sweetened milk to people. The festival of Gurupurab is all about serving and contributing to the society. An example of this is the Bangla Sahib Gurudwara in Delhi which dishes out 10,000 meals a day in ‘langer’, without any cost. The practise of serving ‘langer’ is followed in Gurudwaras across the world, be it Australia, Canada, Germany or France.
