Uposatha
Uposatha refers to a Buddhist observance day that occurs four times a month on the full, new, and quarter moons. These days are dedicated to intensifying religious practice, reflecting a commitment to the Dharma. Lay followers typically observe Uposatha by taking a set of eight precepts, which are more stringent than the standard five precepts. These eight precepts include abstaining from killing, stealing, sexual misconduct, false speech, intoxicants, eating after midday, singing, dancing, music, and adornments, and sleeping on a high or comfortable bed. The purpose of observing Uposatha is to cultivate mindfulness, concentration, and wisdom, and to gain merit. Many Buddhists also spend Uposatha days visiting monasteries, listening to Dhamma talks, and meditating. The observance is a way for laypeople to experience a more monastic-like lifestyle for a day and to strengthen their spiritual discipline. The tradition of Uposatha is ancient and has been practiced throughout Buddhist history in various traditions.
