This from MahaSangha News:

His Holiness Karmapa has dedicated his leadership and responsibility to engaging people from around the world to come together and pray for universal peace. As an extension of the Kagyu Monlam held annually in Bodhgaya, India the first North American Kagyu Monlam provides people of the world an opportunity to generate loving-kindness and compassion through aspirational prayers.

“Kagyu Monlam is an avenue whereby we can spread, at times of great need, the genuine spirit of love and compassion to all the people of the world, like a great ripple, first in Bodhgaya, then in Bihar, and so on. As we continuously offer these prayers for world peace, it is our intention and our wish that peace and happiness extend to all.” — His Holiness the 17th Gyalwang Karmapa

The first North American Kagyu Monlam will be hosted by Karma Triyana Dharmachkra, the North American seat of His Holiness the 17th Gyalwang Karmapa, on July 13th – 17th, 2010 and presided over by Khenchen Thrangu Rinpoche.

The Monlam will be streamed live and more details will be forthcoming. Please check here for more information and registration details.
