Vipasana Teacher S.N. Goenka
"Throughout life, one encounters things that one does not like, and is separated from things one likes. The Buddha went to the root of this problem, and discovered the solution (of Vipassana) for liberation from all misery. He realized that we keep reacting to the pleasant and unpleasant sensations we feel on the body, with craving and aversion. And due to these mental impurities or habit patterns, we remain agitated and miserable."
"Dhamma is invaluable. As soon as a fee is charged, it will become the Dhamma of the rich. Those who have money will try to gain peace by paying the highest price. But they cannot gain peace because when Dhamma becomes a commercial commodity, it fails to bring peace. No one should make the mistake, now or in the future, of turning a Vipassana centre into a commercial organization."
