Dhamma Ratana (Jewel of Dhamma) is situated in the OKPO Monastery in Mogok, Mandalay division. Mogok is known as the land of rubies. In 1996 Goenkaji and Mataji gave Anapana instructions for the first course in this centre. From then on, courses are being held here regularly. Accommodations are available for 80 students. Sangha courses (exclusive courses for monks) are also held at the centre, besides 10-day courses, old student courses, and Anapana courses for children. The technique of Vipassana Meditation is taught at ten-day residential courses during which participants learn the basics of the method, and practice sufficiently to experience its beneficial results. There are no charges for the courses - not even to cover the cost of food and accommodation. All expenses are met by donations from people who, having completed a course and experienced the benefits of Vipassana, wish to give others the opportunity to also benefit.
