JHATKA, the Sikh mode of killing an animal for food, also stands for the meal of an animal or bird so killed. Derived, etymologically, from jhat, an adverb meaning instantly, immediately or at once, jhatka signifies a Jerk, snap, jolt or a swift blow. For Sikhs jhatka karna or jhatkaund means to slaughter the animal instantaneously, severing the head with a single stroke of any weapon or killing with gunshot or electrocution. The underlying idea is to kill the animal with the minimum of torture to it.Jhatka is opposed to kuttha that is meat of an animal slaughtered by a slow process in the Muslim way known as halal (lit. legal, legitimate, lawful).
AHIMSA. The term ahimsa is formed by adding the negative prefix a to the word himsa which is derived from the Sanskrit root \'han\', i.e. \'to kill\', \'to harm\', or \'to injure\', and means not killing, not harming, not injuring. The commonly used English equivalent \'non-violence\' is inadequate as it seems to give a false impression that ahimsa is just a negative virtue. Ahimsa is not mere abstention from the use of force, not just abstention from killing and injuring; it also implies the positive virtues of compassion and benevolence because not killing and not injuring a living being implicitly amounts to protecting and preserving it and treating it with mercy.
