Newari Guthi of Sikkim, which is an organisation established with the consent of all the members of Newar community to preserve their age old culture and to revive their cultural values into their new generation and to bind them in one ethnic group. This study sets out to determine the significance of Guthis for Newari community in Sikkim and their role for the preservation of Newari culture and tradition. After reviewing the available articles and conducting a field survey several information have been gathered about the significance and the role of Newari Guthi of Sikkim; the new generations of Newari community are aloof from their cultural values and language for which Guthi is striving hard to bring out the solution for this by introducing Newari language in government schools and opening several schools to learn Newar language. They have started celebrating Mha Puja, Indra Jatra, etc as their important rituals in order to revive their cultural value system. However due to globalisation and influx of modernity, somewhere they are lacking behind to make their culture flourish. The members of Guthi basically consist of elder people only so there is a less participation of younger generations to run the organisation. Guthi should focus on the involvement of young people to fulfil their objectives. Thus, Participation of youngsters is crucial for the successiveness of Guthi.
