According to the tradition of pure Vipassana, courses are run solely on a donation basis. Donations are accepted only from those who have completed at least one ten-day course with S.N. Goenka or one of his assisting teachers. Someone taking the course for the first time may give a donation on the last day of the course or any time thereafter.
In this way courses are supported by those who have realised for themselves the benefits of the practice. Wishing to share these benefits with others, one gives a donation according to one's means and volition. Such donations are the only source of funding for courses in this tradition around the world. There is no wealthy foundation or individual sponsoring them. Neither the teachers nor the organisers receive any kind of payment for their service. Thus, the spread of Vipassana is carried out with purity of purpose, free from any commercialism.
Whether a donation is large or small, it should be given with the wish to help others: 'The course I have taken has been paid for through the generosity of past students; now let me give something towards the cost of a future course, so that others may also benefit by this technique.'
