Buddhist Lent, also known as Vassa, is a three-month period of retreat observed by many Buddhists, particularly in the Theravada tradition. It typically begins on the full moon day of July and ends on the full moon day of October. During this time, monks and nuns often stay in their monasteries to meditate, study, and deepen their practice, while laypeople may also engage in acts of merit-making. The observance of Buddhist Lent is rooted in the teachings of the Buddha, who encouraged his followers to focus on spiritual development during the rainy season when travel was difficult. This period is marked by increased devotion, reflection, and community activities, fostering a sense of unity among practitioners.
