There are five great vows prescribed to followers of Jainism;
ahimsa (non-violence),
satya (not lying),
asteya (not stealing),
brahmacharya (chastity), and
aparigraha (
non-possession). A further seven supplementary vows are also prescribed, which include three
gunavratas (merit vows) and four
shikshavratas (disciplinary vows). The three
Gunavratas are:
Digvrata (limited movements, limiting one's area of activity),
bhogopabhogaparimana (limiting the use of consumable and non-consumable things), and
anartha-dandaviramana (abstain from purposeless sins). The
shikshavratas include:
samayika (vow to meditate and concentrate for limited periods),
desavrata (limiting movement and space of activity for limited periods),
prosadhopavāsa (fasting for limited periods), and
atithi-samvibhag (offering food to the ascetic).
Sallekhana is treated as a supplementary to these twelve vows. However, some Jain teachers such as
Kundakunda,
Devasena, Padmanandin, and Vasunandin have included it under
shikshavratas.
Sallekhana means to properly 'thin out', 'scour out', or 'slender' the passions and the body through gradually abstaining from food and drink.
Sallekhana is divided into two components:
kashaya sallekhana (slendering of passions) or
abhayantra sallekhana (internal slendering) and
kaya sallekhana (slendering the body) or
bahya sallekhana (external slendering). It is described as "facing death voluntarily through fasting". According to
Jain texts,
sallekhana leads to
ahimsa (non-violence or non-injury), as a person observing
sallekhana subjugates the passions, which are the root cause of
himsa (injury or violence). ==Conditions==
