Donyi-Polo is an indigenous religious faith practiced by the Tani tribes of Arunachal Pradesh, India, and some parts of Tibet. The religion, deeply rooted in nature worship, centers around the veneration of the Sun (Donyi) and the Moon (Polo), representing the cosmic balance between male and female energies. For centuries, Donyi-Polo has been an essential part of the socio-cultural fabric of the Adi, Apatani, Galo, Nyishi, Tagin, and other Tani tribes, influencing their worldview, traditions, and moral values.
In recent times, Donyi-Polo has seen a revival due to efforts by indigenous organizations seeking to preserve their traditional faith amidst increasing external influences, including Christianity and Hinduism. This article explores the history, beliefs, rituals, and contemporary relevance of the Donyi-Polo religion.
Historical Background
The origins of Donyi-Polo can be traced to ancient animistic traditions practiced by the Tani tribes for thousands of years. These tribes, belonging to the greater Tibeto-Burman linguistic group, have historically lived in the Eastern Himalayan region, maintaining a close relationship with nature.
Unlike organized religions with centralized scriptures and institutions, Donyi-Polo is a decentralized faith, transmitted orally through folk songs, myths, and rituals. The Adi and Nyishi people believe their ancestors received divine wisdom directly from nature, which helped them establish a moral code based on truth, honesty, and respect for natural forces.
During the colonial period, Christian missionaries introduced new religious influences in the region. Later, Hindu organizations like the Rashtriya Swayamsevak Sangh (RSS) also made efforts to assimilate indigenous beliefs into Hinduism. However, indigenous leaders like Talom Rukbo (considered the father of Donyi-Polo revivalism) initiated movements in the 1980s to safeguard their traditional religious identity.

Core Beliefs and Philosophy

Contemporary Relevance of Donyi-Polo

As Arunachal Pradesh and the world grapple with ecological and cultural transformations, Donyi-Polo’s teachings offer timeless wisdom on harmony, respect for nature, and the preservation of indigenous identity.
By embracing its core values and adapting to contemporary realities, Donyi-Polo can remain a vibrant and relevant tradition for future generations.
