Earlier this week, President Biden issued a Statement (full text) extending warm wishes to Buddhists in the United States and around the world celebrating Vesak. The Statement says in part:
This sacred day is a time to reflect on the Buddha’s teachings, including the need to work for peace and justice, recognize our common humanity, respect and preserve the nature that surrounds us, and cultivate humility and compassion.
Vesak was celebrated this year on May 16.
