In Jainism this practice is collectively known as
Varshayog and is prescribed for
Jain monasticism. Wandering monks such as
mendicants and
ascetics in
Jainism, believe that during the rainy season, countless bugs, insects and tiny creatures that cannot be seen in the naked eye take birth massively. Therefore, these monks reduce the amount of harm they do to other creatures so they opt to stay in a single place for the four months to incur minimal harm to other lives. These monks, who generally do not stay in one place for long(59 nights for females, 29 nights for males), observe their annual 'Rains Retreat' during this period, by living in one place during the entire period amidst lay people, observing a
vow of silence (
mauna), meditation, fasting and other austerities, and also giving religious discourses to the local public. During the four-month rainy-season period, when the mendicants must stay in one place, the chief
sadhu of every group gives a daily sermon (
pravacana,
vyakhyana), attended mostly by women and older, retired men, but on special days by most of the lay congregation. During their eight months of travel, the
sadhus give sermons whenever requested, most often when they come to a new village or town in their travels. One of the most important Jain festivals,
Paryushana, falls during the beginning of this period, which concludes with Forgiveness Day,
Kshamavani Diwas, wherein lay people and disciples say
Micchami Dukkadam and ask forgiveness from each other. Amongst
Jain merchants, there is a tradition of inviting monks to their respective cities during Chaturmasya to give religious instruction. In Jainism, the third part of the classical
Jain text Kalpa Sutra, written by
Bhadrabahu I in the 4th century BCE, deals with rules for ascetics and laws during the four months (chaturmas) of the rainy season, when ascetics temporarily abandon their wandering life and settle down amidst the laity. This is the time when the festival of Paryushan is celebrated and the
Kalpasutra is traditionally recited. ==Buddhism==
