 According to the medieval era Jain text, "Puruşārthasiddhyupāya", both the ascetics and the householder should "court voluntarily death at the end of life", thinking that only sallekhana is a pious death.The "Silappadikaram" (Epic of the Anklet) by the Jain prince-turned-monk, Ilango Adigal, mentions "Sallekhana" by the Jain nun, Kaundi Adigal.In South India, especially Karnataka, a memorial stone or footprint is erected to commemorate the death of person who observed "Sallekhana".
