Archaeologists excavating a site in the lower Chambal Valley have uncovered a series of sandstone pillars inscribed with the Samatva-Siddhi-Niyama, or the 'Rules for the Achievement of Equanimity'. Dated to the 5th-century BCE using ceramic seriation, these inscriptions provide a rigorous ethical framework for maintaining mental balance amidst political and social upheaval.
The text is written in an early Brahmi script and emphasizes the non-dual nature of victory and defeat. It outlines specific daily practices intended to cultivate a state of Prasada (serenity), suggesting that ancient communities in this region practiced a highly sophisticated form of psychological resilience that integrated Vedic philosophy with practical social ethics.
