“Question-19: What is the significance of Paryushana?

Answer-19: Paryushana means to stay closer, to stay closer to the self - to our soul (Ätmä). Paryushana parva consists of eight (Shwetambar tradition) to ten days (Digambar tradition) . During that period, Jains practice various restraints like not eating (fasting) or eating only one meal a day and spend more time spiritually (like listening to Jain gurus, reading religious books, etc.). The last day of thie period is called Samvatsari (annual ceremony of atonement), when people undertake atonement of wrong activities during the previous 12 months. They admit their sins and pray for forgiveness (ksama). Admission of sins and praying for forgiveness are directed towards the spiritual teachers, family members, friends and others regardless of age or sex. Letters are written to the people they know and who were not approachable in person on the Samvatsari day acknowledging the wrong doings and seeking the forgiveness. The aspirant on his part gives forgiveness to all living beings and asks for the same favor from others. This is usually done through the Samvatsari Pratikraman (Pratikraman means to return from sins or faults) and raises the real spirit of universal friendship and goodwill: (Khämemi savvajive savve Jiva khamantu me ! Mitti me savvabhuesu veram majjha na kenai (It means - I forgive to all living beings; may all of them forgive me.I have a friendship with all living beings and hostility towards none). The pratyäkhyäna (renunciation of certain things) aspect is very elaborate during the Paryushana parva. The Samvatsari Pratikraman is considered a highly important practice during the Paryushana parva which is the most important Jain festival.”
