“Born a sheltered prince, Shakyamuni went out into the world to confront and overcome human suffering,” said the Secretary-General in his message on the occasion.

“This message of compassion is timeless,” he said.

Vesak, the Day of the Full Moon in the month of May, is the most sacred day to millions of Buddhists around the world.

It was on the Day of Vesak two and a half millennia ago, in the year 623 B.C., that the Buddha was born. It was also on the Day of Vesak that the Buddha attained enlightenment, and it was on this Day that the Buddha in his eightieth year passed away.

Further in his message, Guterres also emphasized that in on Tuesday's interconnected world, there can be “no peace as long as others are in peril, no security as long as others suffer deprivation [and] no sustainable future until all members of our human family enjoy their human rights.”

“On this Day of Vesak, let us celebrate the wisdom of Lord Buddha by taking action for others with a strong spirit of solidarity,” noted the UN chief, extending his wishes to all those celebrating the occasion.

In 1999, the UN General Assembly adopted a resolution in which it recognized the International Day to acknowledge the contribution that Buddhism, one of the oldest religions in the world, has made for over two and a half millennia and continues to make to the spirituality of humanity.
