Animal sacrifice among Nihang Sikhs
Ritual slaughter [discuss] of animals (mostly goats) which employs technique of Jhatka is practiced by certain sects within Sikhism on certain religious events. This sacrifice is now only popular among Nihangs and Hazuri Sikhs  who sacrifice goats on the festivals of Diwali and Hola Mohalla and distribute it as Mahaprashad  among the congregants as part of Langar.
Origin of sacrament
|“||"The tradition traces back to the time of Sri Guru Hargobind Sahib Ji who started the tradition of hunting for Sikhs...The tradition of ritually sacrificing goats and consuming Mahaparshad remains alive not only with the Nihang Singh Dals, but also at Sachkhand Sri Hazoor Sahib and Sachkhand Sri Patna Sahib (two of the Sikhs holiest shrines).

The introduction of this religious rite is traced by Hazuri Sikhs to Guru Hargobind. It is said that this sacrifice was also performed by Guru Gobind Singh on the founding day of the Khalsa on his own followers. It should be kept in mind certain sections of modern Sikhs do not approve of this sacrificial ritual.
Tilak sacrament at Hazur Sahib
|“||"When performing Jhatka on a goat, first the goat is bathed, then Japji Sahib and Chandi di Var are read. One Singh stands by the head of the goat and upon the final lines of Chandi di Var being read, ‘Those who sing this divine ballad will be liberated from the realm of life and death’, at this moment the goat is decapitated with one blow and the soul of the goat is liberated."||”|
The ritual begins with bathing the sacrificial goat with water. While the water is being poured on the goat, liturgical recitations from the Sikh scriptures of Japji Sahib and Chandi di Var are practiced. Thereafter, the goat is taken in the middle of the Gurudwara compound. One Nihang Singh holds the hind legs of the goat while the other slaughters it using Jhatka technique. After this the head of the goat is taken in a saucer and its blood is applied to the weapons of Guru Gobind Singh, which are placed in front of Guru Granth Sahib.
Debate within community
There exists a debate within this community whether or this ritual is part of Gurmat, i.e., within scriptural sanction of Sikh teachings. Some scholars say that this ritual is misunderstood and do not equate it with sacrificial slaughter found in some other religions. There are yet others who regard this ritual to be entirely outside Sikhism. Others, Nihangs and Hazuri Sikhs in particular, however argue the opposite and consider it Manmat, or product of self-willed minds, to regard Tilak sacrament not to have come directly from Sri Hargobind Sahib.
