After the 11th century, Nishidhis are inscribed on slabs or pillars with panels and symbols. Rice have dated it to 840 or 869 CE by its textual context.
These slabs or pillars were frequently erected in mandapas (pillared pavilions), near basadi (temples), or sometimes as an inscription on the door frame or pillars of the temple. In Shravanabelgola, the Kuge Brahmadeva pillar has a Nishidhi commemorating Marasimha, another Western Ganga king.
Sallekhana is divided into two components: Kashaya Sallekhana (slenderising of passions) or Abhayantra Sallekhana (internal slendering) and Kaya Sallekhana (slenderising the body) or Bahya Sallekhana (external slendering).
Sallekhana is always voluntary, undertaken after public declaration, and never assisted with any chemicals or tools.
For a successful sallekhana, the death must be with "pure means", voluntary, planned, undertaken with calmness, peace and joy where the person accepts to scour out the body and focuses his or her mind on spiritual matters.
For example, celibacy is one of the Five vows, and ritual death is considered better than being raped or seduced or if the mendicant community would be defamed.
It is believed that a large number of Nishidhis at Shravanabelgola follow the earlier tradition. Its importance as an ideal death in the spiritual life of householders ceased by about the 12th century.
Several inscriptions after 600 CE record that Chandragupta Maurya ( An undated inscription in old Kannada script is found on the Nishidhi from Doddahundi near Tirumakudalu Narasipura in Karnataka. The practice was revived in 1955 by the Digambara monk Acharya Santisagara.
The ancient Svetambara Jain text Acharanga Sutra, dated to about 3rd or 2nd century BCE, describes three forms of Sallekhana: the Bhaktapratyakhyana, the Ingita-marana, and the Padapopagamana.A ritual death under these circumstances by consuming poison is believed to be better and allows for an auspicious rebirth.Giving up solid food by degrees, one should take to milk and whey, then giving them up, to hot or spiced water.The fasting causes thinning away of body by withdrawing by choice food and water to oneself.As death is imminent, the individual stops all food and water, with full knowledge of colleagues and spiritual counsellor.
