Example Input: Question: How much time was between the periods? Passage:Prior to Nepal's unification, Srestha was a collective high-status title given to those Hindu clans referred to as 'Bhaju' (from Sanskrit bhadralok) who served as the key non-Brahmin class of ruling, administrative and merchant class of the Malla courts. From within this broad Srestha groups are two distinct caste groups. First, they count among them the high-caste aristocratic Kshatriyas, locally pronounced as Chathariya, who are descended from the nobles and courtiers of the Malla period and consist of the ruling, land-owning and literate Hindu caste group of the Nepal Mandala, which later formed the core of government bureaucracy during the Shah and Rana period. Second, Srestha title is also attributed to the Panchthariya, who now mostly write their surnames as 'Shrestha', who were historically the Hindu merchant clans of the Valley, as opposed to the Buddhist merchant caste of Uray. These Panchthariyas have Vaishya status in the traditional varna framework. Srestha group has also incorporated in it the socially upward Jyapu farmers and other peasants especially outside the Valley as a means of the Sanskritisation process, although their status is not accepted by the upper-level Srestha castes.
