Esala Full Moon Poya is observed annually on the full moon of the eighth lunar month, primarily in Sri Lanka. This significant day commemorates two key events in Buddhist history: the Buddha's first sermon and the arrival of the sacred Tooth Relic in the country. It is a time for reflection, spiritual practice, and community gatherings, where many devotees visit temples, offer alms to monks, and engage in meditation. The day emphasizes charitable acts and encourages individuals to observe the Five Precepts. Organizations such as the Mahabodhi Society and the Buddhist Publication Society promote educational programs and monastic support during this observance. Esala Full Moon Poya is marked by a focus on spiritual significance rather than commercial activities.
