The Buddhist lent or entering
the rain retreat (Vassa)
The Buddhist lent or entering the rain retreat in Pali language call Vassa what the Buddhists in the western familiar with.
In rainy season, going to anywhere is very difficult. Especially the Sangha missionary who seek for salvation go for giving a sermon to people they sometime stepped on the grain that made people to blame on them. Indian people, in the ancient time, also grow rice. The Buddha gave regulation that the Songha order (monks/Bikshu) cannot go for that sake for 3 months, in rainy season. They have to stay in the temple where they made a wish to stay until the end of the rain retreat.
The Buddhist lent or entering the rain retreat is set on the first day of the waning moon in the eight month. People go to the temple for doing merit, observing religious precepts and meditating. It said that very important day for the country people. People, generally, allow their sons to enter the priesthood during these days so they come for visiting and offering food for all monks in the temple too.
