Some of the world's prominent spiritual leaders and activists are coming to Vancouver to join the Dalai Lama at a peace summit in September.

Victor Chan, the co-founder of Vancouver's Dalai Lama Centre for Peace and Education, said five Nobel Peace Prize laureates have confirmed their attendance, including Archbishop Desmond Tutu, whom he calls the "soul brother" of the Dalai Lama.

"Tutu is pushing 80. His holiness the Dalai Lama is now 74 this year.… Their collected wisdom between the two of them is something that is quite incredible to behold," Chan told CBC News on Tuesday morning.

The event, entitled Vancouver Peace Summit: Nobel Laureates in Dialogue, will take place Sept. 26-29 at the Chan Centre at UBC and the Orpheum Theatre in Vancouver.

Other guests scheduled to speak include:

• Eckhart Tolle, author.
• Jane Goodall, chimpanzee researcher.
• Mia Farrow, actress and activist.
• Matthieu Ricard, buddhist monk.
• Mary Robinson, former Irish president.
• Dr. Wangari Maathai, tentatively, environmental activist and the first African woman to receive the Nobel Peace Prize.
• Betty Williams and Mairead Corrigan, co-recipients of the Nobel Peace Prize in 1976 for their work to end violence in Northern Ireland.

• Maria Shriver, broadcaster, author and chair of the Special Olympics.

Tickets are expected to go on sale in late May or early June, said Chan.
