The diversity in Nepal in terms of ethnicity again makes room for various sets of customs. Although some customs have merely been converted to habits without thought, ancient texts justify them with far-fetched reasons, sometimes making sense and sometimes not.

Most of these customs go back to the Hindu and Buddhist traditions. Among them, the rules of marriage are particularly interesting. In traditional families marriage deals are arranged by parents after the boy or girl come of age. Child marriage and polygamy that were once upheld and accepted with glee are not allowed by the law anymore.

Nepalese do not eat beef. There are several reasons for this, one being that the Hindus worship Cow. Cow is also the national animal of Nepal. Buffalo meat is a good substitute but is only eaten by a certain section of the population.

Another interesting concept among Nepalese is the division of pure and impure. 'Jutho,' referring to food or material that contains another's saliva, is considered impure by Nepalese.. Nepalese consider cow dung to be pure for cleaning purposes. During menstruation women are considered impure and hence, are kept in seclusion until their fourth day purification bath.
