Pavarana day

Pavarana is a Buddhist holyday celebrated on Aashvin full moon of the lunar month. It marks the end of the 3 lunar months of Vassa, sometimes called "Buddhist Lent". This day marks the end of the rainy season in some Asian countries like Thailand, where Theravada Buddhism is practiced. On this day, each monk (Pali: bhikkhu) must come before the community of monks (Sangha) and atone for an offense he may have committed during the Vassa.

For the duration of Vassa, monastics remain in one place, typically a monasteries or temple grounds. In some monasteries, monks dedicate the Vassa to intensive meditation. Some Buddhist lay people choose to observe Vassa by adopting more ascetic practices, such as giving up meat, alcohol, or smoking. While Vassa is sometimes casually called "Buddhist Lent", others object to this terminology. Commonly, the number of years a monk has spent in monastic life is expressed by counting the number of vassas he has observed.

Most Mahayana Buddhists do not observe Vassa, though many Son/Thien monks in Korea and Vietnam do observe an equivalent retreat of three months of intensive practice in one location.

In India, where Buddhism began, there is a three-month-long rainy season. According to the Vinaya, in the time of the Buddha, once during this rainy season, a group of normally wandering monks sought shelter by co-habitating in a residence. In order to minimize potential inter-personal strife while co-habitating, the monks agreed to remain silent for the entire three months and agreed upon a non-verbal means for sharing alms.

After this rains retreat, when the Buddha learned of the monks' silence, he described such a measure as "foolish." Instead, the Buddha instituted the Pavarana Ceremony as a means for dealing with potential conflict and breaches of disciplinary rules (Patimokkha) during the vassa season. The Buddha said:

I prescribe, O Bhikkhus, that the Bhikkhus, when they have finished their Vassa residence, hold Pavâranâ with each other in these three ways: by what [offence] has been seen, or by what has been heard, or by what is suspected. Hence it will result that you live in accord with each other, that you atone for the offences (you have committed), and that you keep the rules of discipline before your eyes.

And you ought, O Bhikkhus, to hold Pavâranâ in this way:

Let a learned, competent Bhikkhu proclaim the following ñatti [motion] before the Samgha: "Let the Samgha, reverend Sirs, hear me. To-day is the Pavâranâ day. If the Samgha is ready, let the Samgha hold Pavâranâ."

Then let the senior Bhikkhu adjust his upper robe so as to cover one shoulder, sit down squatting, raise his joined hands, and say: "I pronounce my Pavâranâ, friends, before the Samgha, by what has been seen, or by what has been heard, or by what is suspected; may you speak to me, Sirs, out of compassion towards me; if I see (an offence), I will atone for it. And for the second time, &c. And for the third time I pronounce my Pavâranâ (&c., down to) if I see (an offence), I will atone for it."

Then let (each) younger Bhikkhu adjust his upper robe...
