Mogok Sayadaw U Vimala was a renowned Theravada Buddhist monk and Vipassana meditation master. He enrolled as a novice monk at age 9 under Sayadaw U Jagara. In 1921, he was ordained as a bhikkhu with the dhamma name of Vimala. As his monkhood was sponsored by the residents of Mogok, a town well known for rubies and gems, Ven. Vimala became known as Mogok Sayadaw. In 1924, Ven. Vimala became the Chief Abbot of Pikara Monastery. He began to give sermons focusing on the Abhidhamma and to teaching Vipassana meditation. The Mogok technique, developed and taught by Mogok Sayawdaw, elaborates on Buddha’s teachings and emphasizes on the awareness of ‘Arising’ and ‘Passing away’ of everything, i.e., ( Impermanence or anicca) in body and mind. Sayadaw is known for his exposition of Paticcasamuppada (Dependent Origination), Samsara (endless rounds of rebirth) and the importance of practicing meditation Vipassana. Mogok Sayadaw passed away in October 1962. He was believed by many to have been an Arahant.
