The two are taking your questions on a Facebook page (or here on mobile). Questions will be compiled into a list that readers can vote on. Winning questions will be answered by the South African archbishop and the Buddhist leader.
The two will meet in Dharamshala, India, April 20-24 not only to celebrate the Dalai Lama’s 80th birthday but also to collaborate on the book. Co-writer Douglas Abrams, who worked with Desmond Tutu on a children's title, God's Dream, will interview the two about their perspectives on joy. Videos of their discussions will be shared with the world after their meeting.
As Douglas told Publisher's Weekly Desmond Tutu and the Dalai Lama "are two of the most infectiously happy people on the planet, and they are willing to share what they have learned with the rest of us."
The Book of Joy: Finding Enduring Happiness In an Uncertain World will be published in 2016 by Avery Books, a Penguin Random House imprint focused on wellness and health.
