 A yearly, elaborate penitential retreat called ""samvatsari pratikramana"" is performed on this day.After the "pratikramana", Jains seek forgiveness from all the creatures of the world, including friends and relatives by uttering the phrase — "Micchami Dukkadam" or its variants like "Khamau Sa", "Uttam Kshama" or "Khamat Khamna".Samvatsari is derived from the Hindi word ""Samvatsara"" which itself has its origin in the Sanskrit language.
