According to the rehat maryada booklet , Kuttha the meat prepared by the Muslim ritual killing is prohibited for a Sikh, regarding eating other meat, it is silent. Siri Guru Granth Sahib Ji (SGGS) makes various references to not eating meat but since it does this in a subtle way this has been ignored by many. Unless you are 'naam-abyasee' then you cannot begin to understand the implications of meat consumption, alas the majority of Sikhs today are so engrossed in daily life and activity and their access to Sikh principles are through the internet or hearsay that most have a very eskew idea of their faith. And lets face it, if you enjoy chicken kebab then you are going to listen and agree with those arguments that allow you to indulge, it is only a blessed soul who will really understand the arguement against meat and act upon it.
Many 'modern' Sikhs will say that man as a hunter gatherer evolved with a meat diet and that infact it was the meat diet that increased the size of the human brain that let to the superiority of man. Now, it is true that man has evloved over the ages, but if he was a monkey once does he still have to retain the monkey urges? If man can now survive quite adequately without a meat diet and man knows that eating meat slows his spiritual progress then is that not enough to refrain from this act? Only we have the capacity to evolve spriritually, and to do this we must have dicipline and fortitude. As for meat being an essential part of our diet, there are millions of vegiertians and vegans who would disagree.
One 'evidence' the pro-meat lobby will site is that Guru Hargobind Sahib ji and Guru Gobind Singh Ji were accomplished hunters, if they hunted then so can we, "if they hunted meat then they must have consumed it, right ?" Wrong.
Firstly our ego filled minds bring down our glorious Gurus to our level, we treat them as if they were like one of us, they were not. They were the divine light and what acts they performed we can only stand back in awe, we can never emulate what they did. Guru Hargobind Sahib Ji recited one thousand shabads every day as part of their daily routine, can we even begin to emulate this? Yet we are all so quick to make assumptions that if the Gurus hunted then so can we, and then consume it.
The author of a called Sikh & Sikhism writes about the Gurus hunting, he states : "The game would have been cooked and put to good use, to throw it away would have been an awful waste."
The author provides no evidence to back up his claim, pure conjecture. We cannot see past the physical world, the Guru's were pure souls, at One with the Almighty. Guru Gobind Singh Ji in his glorious autobiography Bachittar Natak writes that after many eons of tapasia (meditation) the two (Guru Ji and God) became One. There is no doubt that Guru Sahib Ji had merged with the Almighty. If a glass of water is poured into the ocean who is to say which part is now the water from the glass and which is not, it becomes one, in the same way the Guru's were at One with God. Where ever they went they granted mukhti (salvation) to all who were ready to take it. Guru Nanak Dev Ji on his udasis's (journeys) saved such people like Sujjan Thug - who would invite people to his house and then in the dead of night strangle them, Kaudda Rakhsh, who indulged in cannibal activites and Walli Quandhari the mean fakir who would not let anyone use his well. So, from the very begining the Guru's have been blessing and granting mukhti to those souls whose karmic circle needed breaking, and who can do this ? Only the True Guru.
In the same way Guru Hargobind Sahib Ji and Guru Gobind Sahib Ji went hunting, not for pleasure - for the Guru's were way above the pleaseures of this world - or the need to satisfy their taste buds, they were above this also , it was to instill a sense of pride and self confidence in the downtrodden people of India who for centuries had grovelled to any invader who happen to come their way. Guru Sahib Ji indulged in royal activities, like wearing of the Kalgi, jewelled plumes on the turban, use of the chaur sahib, as symbols of royalty, not because Guru Ji had any need for these superfluouse items, but rather to instill a sense a self pride within the ordinary Indian, and also in the process to settle long overdue 'accounts', to release the souls of the poor unfortunate animals who may have wronged in the past, to grant them Mukti (salvation).
There is a story of Guru Gobind Singh Ji who sent out his white falcon to hunt an animal, once caught Guru Ji watched as the baaj tore into the animals flesh. Asked by one of his Sikhs what was the reasoning behind this Guru Ji stated that in a previous life this animal was a man and had borrowed some money from the baaj and swore on Akal Purkhs name that he would pay it back, he never did and now it was pay back time. There are many instances like this which illustrate that the Gurus were not hunting for meat but to save these souls from the continuous cycle of birth and death. In two Hukamnamas of Sri Guru Hargobind Sahib Ji there are clear cut instructions prohibiting the eating of meat, fish etc.
