This first sermon is not only the first structured discourse given by the Buddha after his enlightenment, it also contains the essence of all his subsequent teaching. At the end of the talk, one of the five participants recounted his understanding of what had been said and asked to be received as a disciple, a request the Buddha granted, thus establishing the first order of monks.
The day is observed by donating offerings to temples and listening to sermons. The following day is known in Thailand as Thai: วันเข้าพรรษา Wan Khao Phansa; it is the first day of Thai: พรรษา vassa, the Theravada rains retreat.
In Indonesia, this festival is centered at Mendut Temple, near Borobudur.
