Significance of full moon days through the year – Venerable Bataduwe Santha Samana


Even before Gautama Buddha was born, full moon days have had special significance to people of the ancient times. There is evidence to suggest that people of the ancient times did engage in various religious activities at least once a week to make their spiritual lives better for both herein and here after.  With no almanacs or calendars to refer, lunar month was the only time reference available to them to determine the day of the week that would be set aside for religious activities.

By the time of the Buddha, the various ascetics were already making weekly religious observances on a day set aside for such practices. From the time of the Buddha’s first discourse, monks did offer dhamma discourses at times and the disciples frequented the places where the monks were residing to meet the monks. Yet no special day was set-aside for these visits to meet the monks. The other ascetics however having set aside time for such meetings gave rise to better bonding between the lay people and the ascetics.

King Bimbisara who was a very devout disciple of the Buddha. Having observed the practice of the ascetics, and keeping in mind the betterment of the community of sangha, suggested to the Buddha that it would be appropriate to set aside days for such spiritual activities. Having considered the suggestion the Buddha did prescribe four such meetings in each lunar month. This was the genesis of spiritual observances on full moon days.

It just so happened that even though the laity and the monks did meet on full moon days as prescribed by the Buddha, no discourses were habitually forthcoming from the monks. The laity was not very happy about it. The Buddha having noticed this displeasure then prescribed that the monks should offer discourses on a regular basis on such days.

One day, the devout disciple Visakha mentioned to the Buddha that she observes the higher order precepts on the full moon days. Using this as a trigger, the Buddha exalted the virtues of this practice and prescribed it to all those who were following his teachings. This practice has continued to this day
amongst devout Buddhists.

Spiritually, observance of the higher order precepts became a very strong practice. So much so, that according to the Buddha even non-human deities has taken the time to see this strong practice amongst the humans.

The full moon day is determined according to the almanac. The phase of the moon is determined according to a system of mathematics that has prevailed from the ancient Vedic days. The day of no moon comes 15 days following the day of the full moon. The waning moon is observed after 8 days from the full moon day and the waxing moon occurs after 8 days from the day of the no moon. These 4 days are typically set aside for spiritual practices.

Today according to the Julian calendar, year is divided into 12 months. Each month typically has a corresponding full moon day. These are described as follows. They have significance due to various events that took place either on those days or close to those days.

January – Duruthu

The Buddha’s first visit to Sri Lanka coincided with the Duruthu full moon day. According to the chronicles, He visited ‘Hela Diva”, as Sri Lanka was then known, on the 9 th month following enlightenment. The purpose of the visit was to subdue and tame the ‘yaksha’ and the ‘naga’ tribes inhabiting the area today known as Mahiyangana, on the bank of the river ‘mahaveli’ It is said that the deity named ‘Sumana Saman’ residing in the mountain called ‘Samanola’, today known as the Adam’s peak, reached the stage of sotapanna having listened to the discourses offered by the Buddha.

Arahath Saripuththa and Moggalana were proclaimed as the Chief Disciples in the month of Navam.

It is also in the month of Navam that the Buddha decided for the first time to set down a set of advisories to ensure the harmony and the discipline of the community of Sangha. These are known as Vinaya Kamma.

For the first 20 years, there was no cause to prescribe advisories due to the abundance of monks who had reached enlightenment through effort and diligence. With the influx of many from varied backgrounds into the community of the sangha, for a multitude of reasons, it was deemed necessary to enact these advisories to safeguard the purity, integrity and the harmony within the community of sangha. The very first set of advisories touched various aspects including the virtue of patience, not harming self and others, discipline of the faculties, overcoming the five hindrances, intake of food, not clinging to the various places of abode and being pleasant to others. The Buddha never admonished without a valid reason; and the reasons given shows the degree to which the community of sangha was subject to vagaries and external influences, even during the time of the Buddha.

It was also on the full moon day of this month that at the age of 80, He stated that in three months from that point in time He would relinquish this life cycle never to be born again.
