IN CONCLUSION, Hinduism has played a huge role in Indonesia that had transformed the Nusantara into a Hindu archipelago with rich culture diversity and organized society (during the pre-colonial era in the 16th century). The Sanskrit Verda scriptures and the universal epics of Ramayana & Mahabharata had created numerous positive influences in the civilization, including a revolution in religious faith (replacing barbaric ancestor worships) through ethics, enhancing variety and developing arts, cultures, and traditions, creating civilized society and/or kingdoms, and promoting unity, nationalistic pride, and peace within the Nusantara.
