Praying at the Saga Dawa Festival.
Saga Dawa means ‘fourth month’, and it is on the 15th day of this month on the Tibetan calendar that Tibetan and Nepalese Buddhists celebrate both his birth and the day when he died and attained Nirvana.
Religious observance is influenced and shaped by the culture in which it is practised. During Saga Dawa, people flock to villages and monasteries turning their prayer wheels and singing and dancing. It is also a festival of light, where butter lamps abound. Although picnics are common, as a day of strict Buddhist observance no meat is allowed.”
