A recent excavation in the Luni River Basin of Rajasthan has unearthed a cache of terracotta seals dating back to the 5th century BCE. These seals, inscribed with a transitional Brahmi script, refer to the 'Rta-Chakra' or the 'Wheel of Cosmic Order,' and outline a sophisticated early Vedic philosophy centered on cyclic reciprocity between human action and natural phenomena.
The inscriptions suggest that the inhabitants of this region viewed moral conduct (Dharma) not merely as a social contract, but as a biological and environmental necessity to maintain the 'rhythm' of the river and seasonal patterns. This discovery provides crucial archaeological evidence for the early integration of ecological ethics into Sanatan Dharma's philosophical core.
