Fasting is very common among Jains and as a part of festivals.  Most Jains fast at special times, during festivals, and on holy days.  Paryushan is the most prominent festival, lasting eight days in Svetambara Jain tradition and ten days in Digambar Jain tradition during the monsoon.  The monsoon is a time of fasting.  However, a Jain may fast at any time, especially if he or she feels some error has been committed.  Variations in fasts encourage Jains to do whatever they can to maintain whatever self control is possible for the individual.  According to Jain texts, abstaining from the pleasures of the five senses such as sounds and dwelling in the self in deep concentration is fasting ("upavāsa").
