Two large groups distributed in scattered patterns all over the country, which are considered the two highest castes in Nepal. They have sharp Indo-Aryan features and an olive complexion. Brahmins are believed to have migrated from India while Chhetris are from the present day Khasa people from Khasi. These people follow Hinduism as their main religion and socially they have many sects. They are divided into two major streams, the Purba and Umai. The Kumain people are of the origin of Kumo, Northern India, Uttar Pradesh. Their social practices depend upon Hindu religious epics. They speak Nepali, the national language of Nepal and use a script with basis in Sanskrit.The Brahmans are priestly caste. The priests in all Hindu temples are exclusively Brahmans.

The Brahmans and Chhetris are orthodox followers of Hinduism and its rites and rituals mentioned in the Vedas, Purans and other scriptures. Their marriages and other rituals are very complex and elaborate. Sometimes the parents hold marriages for their 11 or 12 years old daughters. Though this is punishable by law; one hardly gets persecuted against such crime. Child marriages, however, tend to slow down among the city dwellers and educated families. Inter-caste marriages are looked down upon and cross- cousin marriages are strictly prohibited. The body of deceased is always cremated. Women never attend the cremation. The pyre is lit by the son of the deceased. It is believed that 'doing so' will set the soul in eternal peace after the death.
