An excavation team in the Ghaggar Basin has unearthed a cache of terracotta tablets dating to the 5th-century BCE, inscribed with a treatise called the 'Maitri-Setu-Vibhaga'. Unlike the predominantly ritualistic texts of the era, this work focuses on a secular philosophy of social connectivity, outlining ethical obligations that transcend caste and lineage to foster communal resilience.
The tablets describe the concept of "The Bridge of Friendliness," a logical framework for resolving inter-tribal conflicts through the recognition of shared metaphysical origins. This find suggests that ancient Sarasvati-region thinkers were developing sophisticated social contracts based on empathy and horizontal networking long before the consolidation of major imperial structures in northern India.
