Copper plate inscriptions dating to the 7th Century CE have been discovered during a temple renovation in the Deccan. Titled 'Prana-Darshana', the plates describe a 'philosophy of breath' that extends beyond the individual to the entire community, positing that the Prana (life-force) of a society is maintained through acts of mutual sacrifice and reciprocity.
The inscriptions detail how the social fabric is woven from the shared vitality of its members, and that 'unethical breathing'—defined as consumption without contribution—leads to the decay of the collective life-force. This discovery offers a unique physiological metaphor for social ethics, typical of the early medieval Deccan's philosophical traditions.
