Vesak (; ), also known as Buddha Jayanti, Buddha Purnima, Buddha Day, is a holiday traditionally observed by Buddhists in South Asia and Southeast Asia, as well as Tibet and Mongolia. It is the most important Buddhist festival. The festival commemorates the birth, enlightenment (Nibbāna), and passing (Parinirvāna) of Gautama Buddha in Theravada, Tibetan Buddhism and Navayana.
The name Vesak is derived from the Pali term or Sanskrit for the lunar month of Vaisakha, which is considered the month of Buddha's birth. In Mahayana Buddhist traditions, the holiday is known by its Sanskrit name (Vaiśākha) and derived variants of it.
In the East Asian tradition, a celebration of Buddha's Birthday typically occurs around the traditional timing of Vesak, while the Buddha's awakening and passing away are celebrated as separate holidays that occur at other times in the calendar as Bodhi Day and Nibbāna Day. In the South Asian tradition, where Vesak is celebrated on the full moon day of the Vaisakha month, the Vesak day marks the birth, enlightenment, and the ultimate passing away of the Buddha.
History
Although Buddhist festivals have centuries-old tradition, the first conference of the World Fellowship of Buddhists held in Sri Lanka in 1950 formalized the decision to celebrate Vesak as the Buddha's birthday across multiple Buddhist countries. The resolution that was adopted at the World Conference reads as follows:
On Vesak Day, Buddhists all over the world commemorate events of significance to Buddhists of all traditions: The birth, enlightenment and the passing away of Gautama Buddha. As Buddhism spread from India it was assimilated into many foreign cultures, and consequently Vesak is celebrated in many different ways all over the world. In India, Vaishakh Purnima day is also known as Buddha Jayanti day and has been traditionally accepted as Buddha's birth day.
In 2000, the United Nations (UN) resolved to internationally observe the day of Vesak at its headquarters and offices.
Celebration
The month of May usually has one full moon, but as there are 29.5 days between full moons, occasionally there are two. If there are two full moons during the month of May, some countries (including Sri Lanka, Cambodia and Malaysia) celebrate Vesak on the first full moon, while others (Thailand, Singapore) celebrate the holiday on the full moon of 4th lunar month. The difference also manifests in the observance of other Buddhist holidays, which are traditionally observed at the local full moon.
On Vesak, devout Buddhists and followers alike assemble in their various temples before dawn for the ceremonial and honorable hoisting of the Buddhist flag and the singing of hymns in praise of the holy triple gem: The Buddha, The Dharma (his teachings), and The Sangha (his disciples). Devotees may bring simple offerings of flowers, candles and joss-sticks to lay at the feet of their teacher. These symbolic offerings are to remind followers that just as the beautiful flowers would wither away after a short while, and the candles and joss-sticks would soon burn out, so too is life subject to decay and destruction. Devotees are enjoined to make a special effort to refrain from killing of any kind. They are encouraged to partake only of vegetarian food for the day. In some countries, notably Sri Lanka, two days are set aside for the celebration of Vesak, and all liquor shops and slaughter houses are closed by government decree during the two days.
Also birds, insects and animals are released by the thousands in what is known as life release to give freedom to those who are in captivity, imprisoned, or tortured against their will. (The practice, however, is banned in some countries such as Singapore, as the released animals are unable to survive long-term or may adversely impact the local ecosystem if they do.)
Some devout Buddhists will wear simple white clothing and spend the whole day in temples with renewed determination to observe the eight precepts.
Devout Buddhists undertake to lead a noble life according to the teaching by making daily affirmations to observe the Five Precepts. However, on special days, notably new moon and full moon days, they observe the eight precepts to train themselves to practice morality, simplicity, and humility.
Some temples also display a small statue of the Buddha in front of the altar in a small basin decorated with flowers, and filled with water or sweet tea for devotees to pour over the statue. This is symbolic of the cleansing of a practitioner's bad karma, and to reenact the events following the Buddha's birth, when devas and spirits made heavenly offerings to him.
