I often recommend a free 10-day vipassana meditation course found at https://dhamma.org . Is it possible that there would be a 10-day meditation retreat that gives you food and lodging for free? Not only that, but would they refuse to accept money prior to taking such a 10-day meditation course? Is that possible? Of course it is possible! You see, they refuse to accept payments before you attend the course but allow you to donate for the next group after you finish.
