A male Rastafarian’s beard is a sign of his pact with God (Jah or Jehovah), and his Bible is his source of knowledge. Leviticus 21:5 (“They shall not make baldness upon their head, neither shall they shave off the corner of their beard, nor make any cuttings in the flesh.”) Likewise, it is not uncommon for a Rastafarian beard to grow uncombed, like dreadlocks.
The Bible states in Leviticus 19:27 that “You shall not round the corners of your heads, neither shalt thou mar the corners of thy beard.” Talmudic tradition explains this to mean that a man may not shave his beard with a razor with a single blade, since the cutting action of the blade against the skin “mars” the beard.
The Sikhs consider the beard to be an integral part of the male human body as created by God and believe that it should be preserved, maintained, and respected as such. Guru Gobind Singh, the tenth Sikh Guru, ordained and established the keeping of the hair as part of the identity and one of the insignia of Sikhs. Sikhs consider the beard to be part of the nobility and dignity of their manhood. Kesh is also one of the Five Ks for a baptised Sikh.
In Eastern Christianity, beards are often worn by members of the priesthood and by monastics, and at times have been required for all believers; see Old Believers. Amish and Hutterite men shave until they are married, then grow a beard and are never thereafter without one, although it is a particular form of a beard (see Visual markers of marital status). Many Syrian Christians from Kerala in India wore long beards.
Nowadays, members of many Catholic religious communities, mainly those of Franciscan origin, use a beard as a sign of their vocation. At various times in its history the Catholic Church permitted and prohibited facial hair. Some Messianic Jews also wear beards to show their observance of the Old Testament.
Hindus keep beards depending on which Dharma they follow. Many Hindu priests are unshaven as a sign of purity. The ancient text followed regarding beards depends on the Deva and other teachings, varying according to whom the devotee worships or follows. Most original idols lack mustaches, except for the Rakshasa and Asuras, who are considered to be bad or power-seeking. Many Sadhus, Yogis, or Yoga practitioners keep beards, and represent all situations of life. Shaivite ascetics generally have beards, as they are not permitted to own anything, which would include a razor. The beard is also a sign of a nomadic and ascetic lifestyle.
Beard hair is most commonly removed by shaving. If only the area above the upper lip is left unshaven, the resulting facial hairstyle is known as a moustache; if hair is left only on the chin, the style is a chin beard. The combination of a moustache and a chin beard is a goatee or Van Dyck, unless the moustache and chin beard are connected, in which case it is known as a circle beard.
