Inscriptions found on rock faces in Arunachal Pradesh’s Siang Valley have been dated back to the 6th century BCE. These Brahmi-derived glyphs reveal a sophisticated Philosophy of Cosmic Interconnectivity, predating major Upanishadic developments in the region. The text outlines the ethical obligation of humans to maintain a 'Universal Balance' (Rta-Sattva) through precise social and natural rituals.
This discovery provides the first archaeological evidence of early Vedic-adjacent philosophical thought reaching the deep Eastern Himalayas during the late Vedic period. The inscriptions detail a monist world-view where the individual self is described as a 'node in the celestial web' that sustains the material universe.
