In the state of Maharashtra, India, the Jain community has lived in many places for the last two millennia. They have a rich heritage of their religious practices, knowledge of indigenous science, technology, and medicine, which is evident through their numerous manuscripts written in local languages, mainly in palm leaves and on paper. The local Jain temples and their adjoining libraries are the repository of a large number of valuable manuscripts. A few existing manuscripts are more than a millennium old and in readable condition. Many centuries-old manuscripts are still in the possession of a few local people. Since ancient times, people have tried to preserve their clan and community treasures of knowledge by writing manuscripts. They had the tradition of copying manuscripts, which they found deteriorated beyond recovery in new leaves or papers and thus, preserved their ancient knowledge for their coming generations. Although many of them deteriorated, on average, they have survived for more than two–three centuries. It is a matter of study to understand the indigenous knowledge of people in the Jain Community, especially in Maharashtra, that they have practised since the last millennium or for some centuries to preserve their manuscripts for a long time. The present paper documents a few natural ingredients and traditional techniques of manuscript preservation among the Jain community.
