History of the Buddhist Lent Day
At the beginning of the Buddha Time, the Buddhist Lent was not appointed, so each monk could teach the congregations throughout the year. Whenever a monk determined that he would like to teach his congregations and he was available, he went to do. Sometimes, some monks did not go out to teach anyone, but they saw some places suitable to meditate, they went to do so. The most places for them were in the forests or on the faraway hills which they had to past the country.
Because of the monks’ traveling and farmers worked in their farms in the rainy season, the monks damaged the farmers’ rice sprouts unintentionally because they misunderstood that the rice sprouts were grass. So, the farmers went to sue the Lord Buddha that the monks damaged their rice sprouts, why the monks did not stay in the temples during the rainy season like birds.
