Roots
Hinduism
In Hinduism, Bali is the ritual killing of an animal. Jhatka is the proscribed method for Hindu Ritual sacrifice, however other methods such as strangulation and the use of a wooden spile (sphya) driven into the heart is used. The reason for this is that priest saw the animal making a noise as a bad omen. Jhatka requires the instant killing of the animal in a single decapitating blow with an axe or sword. Those Hindus who do eat meat prescribe jhatka.
Islam
In Islam, Dhabīḥah (or Zabiha) is, in Islamic law, the prescribed method of ritual slaughter of all animals excluding camels, locusts, fish and most sea-life. This method of slaughtering animals consists of a swift, deep incision with a sharp knife on the throat, cutting the jugular veins and carotid arteries of both sides but leaving the spinal cord intact. It must be done with respect and compassion; avoiding as much as possible any animal pain or discomfort.
Among Sikhs
Ritual Jhatka sacrifice of goats is also practiced by some sections of Sikhs such as Hazuri Sikhs an Nihangs on certain events of religious significance which is condemned among Sikh Society.
