Samyak ( Devanagari: सम्यक) is an almsgiving Buddhist festival celebrated in the Kathmandu Valley in Nepal. During the ceremony which is held on a large open ground, hundreds of images of Dīpankara Buddha are assembled, and gifts of different types of food are made to the deities and the Buddhist community.
Samyak is the most spectacular Newar Buddhist celebration. It is observed at different intervals in the three cities of the valley -- every 12 years in Kathmandu, every five years in Lalitpur and annually in Bhaktapur. The first documented Samyak festival in Kathmandu took place in 1015 AD (135 Nepal Era).
The festival brings together a wide cross-section of Newar society, including priests, artisans, traders, musicians and farmers. Each group has a defined role designed to highlight social harmony. The ceremony celebrates the practice of giving to the Buddhas and monks in the Newar Buddhist tradition. The Samyak festival in Kathmandu is held at Kathmandu Durbar Square and the field of Bhuikhel at the foot of Swayambhu hill.
