Full Moon Day of Waso

What Is Full Moon Day of Waso?

The Full Moon Day of Waso is a significant observance in Theravada Buddhism, primarily celebrated in Myanmar. It marks the commencement of Vassa, also known as the Rains Retreat, a three-month period when Buddhist monks traditionally remain in one monastery. This day is also historically important as it commemorates the delivery of Siddhartha Gautama’s first sermon, the “Dhammacakkappavattana Sutta,” after he achieved enlightenment.

As a public holiday in Myanmar, the Full Moon Day of Waso sees widespread participation from both monastic and lay Buddhist communities. It is a time for introspection, religious devotion, and the reinforcement of ethical practices within the Buddhist tradition. The observance underscores the interdependence between monks and lay followers, who provide for the monks’ needs during their retreat.

History and Origins of Full Moon Day of Waso

The origins of the Full Moon Day of Waso are deeply rooted in Buddhist history and monastic tradition. The practice of Vassa, the Rains Retreat, dates back to the time of the Buddha. During the monsoon season in ancient India, it was customary for wandering ascetics, including Buddhist monks, to halt their travels. This was primarily to avoid inadvertently trampling on young crops or harming insects and other small creatures that were more prevalent during the rainy period. The Buddha established this tradition, decreeing that monks should reside in a single location for the three months of the rainy season.

Beyond the practical considerations, the Full Moon Day of Waso also commemorates a pivotal moment in Buddhist doctrine. It is believed to be the day when Siddhartha Gautama, having achieved enlightenment, delivered his first sermon at the Deer Park in Sarnath, India. This sermon, known as the “Dhammacakkappavattana Sutta” (The Setting in Motion of the Wheel of Dhamma), outlined the Four Noble Truths and the Eightfold Path, forming the fundamental principles of Buddhist philosophy. This dual significance solidifies the Full Moon Day of Waso as a foundational observance in the Buddhist calendar.

How Full Moon Day of Waso Is Celebrated

In Myanmar, the Full Moon Day of Waso is observed with a range of customs and practices that reflect its dual significance as the start of Vassa and the commemoration of the Buddha’s first sermon. The day is marked by heightened religious activity within the community. Lay Buddhists participate actively by visiting pagodas and monasteries to offer alms, food, and other necessities to the monks.

A notable tradition is the offering of “Waso Thingan,” or Waso robes, to monks. These robes are new garments presented to the monastic community in preparation for the Rains Retreat. This act of generosity is considered a meritorious deed, reinforcing the connection between the lay community and the Sangha (monastic order). Many devotees also take special precepts, such as observing the Eight Precepts, which include abstinence from food after midday, dancing, singing, and ornamentation, and sleeping on a high bed. Listening to sermons and meditating are also common activities.

Monks, for their part, formally commence their retreat period on this day. They commit to remaining within their chosen monastery for the next three months, dedicating themselves to intensive study, meditation, and teaching. The public holiday status in Myanmar allows families to spend time together, often engaging in these collective religious practices. The atmosphere is generally one of peaceful devotion and quiet reflection.
