Anyone who has completed at least a 10-day course can volunteer to work in Dhamma service if they so choose, and there is a wide range of service options to choose from.
The giving of Dhamma Service, whether in a course or in some other way to help in the spread of Dhamma, is one of the most valuable experiences a student of Vipassana can have. Not only is it rewarding to know that you have helped others to taste the Nectar of Dhamma, but it also is a wonderful source of growth and strength in one's own development in meditation practice.
Dhamma service is needed more and more as the demand for courses becomes greater in the world. In 2003 there were almost 1400 Vipassana courses conducted around the world in which almost 100,000 students participated. Without the invaluable assistance of hundreds of old students who organized and served these courses, prepared the Centers and non-center course sites and participated in the management and operation of the Centers none of these courses would have been possible.
Without the voluntary assistance of old students who feel a volition to give to others a little of what they have received from their participation in Vipassana courses, the courses cannot be arranged and conducted.
