Sikhs feel that eating meat is immoral, unlawful and simply wrong according to the teachings of Guru Granth Sahib jee.. In Sikhism, only vegetarian food is served in the Gurdwara around the world. There are however small part of community who choose to adopt a meat diet just like there are small majority who do not wear turban as required by Sikh Code of Conduct. Majority of Sikh Religious Organizations such as- Damdami Taksal, Akhand Kirtani Jatha, Guru Nanak Nishkam Sewak Jatha and the 3HO — believe that a Sikh should be meat-free.
Kabir Ji was not a Guru but he was a respected Bhagat, so respected that his bani earned a place in Guru Granth Sahib Ji. His bani should receive same importance as any Bani of the Guru’s in Guru Granth Sahib Ji and over and over he says eating meat is wrong. “Kabeer, those mortals who consume marijuana, fish and wine – no matter what pilgrimages, fasts and rituals they follow, they will all go to hell”
Within the gurdwara, the Guru ka Langar (Guru’s community kitchen) serves purely lacto-vegetarian food. The reason for serving vegetarian food is that the Langar is open to all and to serve healthy food.
God created us to be able to eat both plants and meat, unlike animals which are either typically carnivores or herbivores. But at same time God also made us the only form that is able to reach god, it is in our human form that we are the strongest to overcome our natural instincts. If we are able to overcome the million barriers to reading bani, to being faithful to our partners and doing everything else that our natural instincts don’t normally want us to do. Then why is it so hard to give up our natural instinct to stop eating meat? We are humans, we created to overcome our natural instincts and become one with god.
