Excavations near the ancient port site of Dharanikota in the Godavari Delta have led to the discovery of stone pillar inscriptions containing a treatise called 'Dharma-Kosa-Niyama'. The text, dated to the 4th-Century BCE, explores the philosophy of social and ethical debt (Rna) as a mechanism for distributive equity in early agrarian societies.
Unlike later legalistic interpretations of debt, these inscriptions frame 'Rna' as a cosmic bond that links the individual's prosperity to the well-being of the entire community and the natural environment. The findings provide a rare glimpse into the 'Sanatan Dharma' ethical framework before the consolidation of the major empires, emphasizing a decentralised and highly reciprocal social contract.
