Would the retreat be open to people who would like to join just for, say, a long weekend or a week? I can see the attraction and the benefits of living one's life as part of a monastic order, but there's no way I would give up my husband or family in order to do that full-time. However, I do often wish there was someplace I could go for a few days to meditate, Druid-style, live a simple life, and walk around by myself and enjoy nature. Help with the cooking, obviously, and do the washing-up, sweep floors, clean the windows. I like the idea of a soup-kitchen. Bit of a spiritual-retreat-holiday. I hope that doesn't sound degrading (I certainly don't mean it to be), but about a week or two at a time is probably the most that modern folk with jobs and families can manage, even if they do like the idea of quiet, contemplative living within a community setting.
Wishing you luck and inspiration with this project
If you do found your Druid retreat, my husband and I will certainly come for a week once a year (if it's in Europe).
