Born in Canada, Ven. U Jagara was introduced to Buddhist practice in the early 1970’s by Robert Hoover, and ordained as a monk under the Venerable Mahasi Sayadaw in Burma in 1979. He spent 15 years in Sri Lanka combining meditation with the study of Buddhist texts and periodically traveled to India where he practiced in intense retreats with S. N. Goenka. For several years he conducted retreats in India, America, Europe and Asia in the S.N. Goenka tradition. Since 1995 U Jagara has trained under the guidance of Pa Auk Sayadaw, the Burmese master renowned for his faithful adherence to the Visuddhimagga as both a practical guide to jhana and a detailed exposition of direct analytical approaches to vipassana. U Jagara assists Pa Auk Sayadaw in the teaching.
