The Dalai Lama will make a special appearance at British summer music festival Glastonbury on Sunday, as part of his four-day U.K. tour.

Festival organizers confirmed that the Tibetan spiritual leader will deliver a speech in the Green Fields and explore the farm grounds during his visit on Sunday.

Key themes throughout the visit will be the Dalai Lama's message of compassion, non-violence and the ‘oneness of humanity.'

His visit to the UK comes a week before His Holiness turns 80.

Glastonbury kicked off Wednesday and runs until Sunday.
