"May you all be happy!" 

I took this picture last morning while visiting Bodh Gaya (बोधगया), in the Indian state of Bihar, the place of Gautama Buddha's attainment of nirvana (Enlightenment) and where stands the International Tipitaka Chanting Ceremony which will end the 10th of December .

Eleven-day long chanting prayer ceremony gather hundreds of Buddhist monks and devotees from across the globe for world peace.
Monks and nuns in saffron robes chant scriptures of the ”Tipitaka”, the collected teachings of Lord Buddha in the sacred Pali language, at Mahabodhi temple.
The monks are praying for the prosperity and well-being of all living creatures.
The aim of this prayer is that there should be peace in the world, and prosperity and happiness should prevail among all living beings, said Bhante Dinanand, a monk.
Lord Buddha is said to have attained enlightenment while doing penance under the Bodhi tree in Bodh Gaya where emperor Ashoka built the Mahabodhi temple complex about 250 years after the Buddha’’s enlightenment.

Everywhere I could read: "May you all be happy!"
