Mara or Mrityu Devi is a Sanskrit word meaning "death" or any personification thereof. In Hinduism, Mara is the goddess of death and offerings would be placed at her altar. Though much less popular, some sects of worship do exist in India.
She is an important deity worshipped by ethnic groups across South Asia, including the Kalash people and once by the Nuristani peoples, indicating her prominence in Vedic times.[1][2][3][4] [5] [6]
About half of the Kalash practice a form of Hinduism infused with old pagan and animist beliefs.
Prominent sites include Hadda, near Jalalabad, but Buddhism never seems to have penetrated the remote valleys of Nuristan, where the people continued to practise an som form of Hinduism.
Up until the late nineteenth century, many Nuristanis practised a primitive form of Hinduism. It was the last area in Afghanistan to convert to Islam—and the conversion was accomplished by the sword.
Some of their deities who are worshiped in Kalash tribe are similar to the Hindu god and goddess like Mahadev in Hinduism is called Mahandeo in Kalash tribe. ... All the tribal also visit the Mahandeo for worship and pray. After that they reach to the gree (dancing place).
The Kalasha are a unique people living in just three valleys near Chitral, Pakistan, the capital of North-West Frontier Province, which borders Afghanistan. Unlike their neighbors in the Hindu Kush Mountains on both the Afghani and Pakistani sides of the border the Kalasha have not converted to Islam. During the mid-20th century a few Kalasha villages in Pakistan were forcibly converted to this dominant religion, but the people fought the conversion and once official pressure was removed the vast majority continued to practice their own religion. Their religion is a form of Hinduism that recognizes many gods and spirits and has been related to the religion of the ancient Greeks... given their Indo-Aryan language, ... the religion of the Kalasha is much more closely aligned to the Hinduism of their Indian neighbors that to the religion of Alexander the Great and his armies.
