Thank you for the clarification. I like the rock climbing simile!
In fact, I agree with Bhante Sujato’s posts linked earlier in the thread and I’m against a D&D practice thread.
However, I’d love to have a small practice PM group. I agree there are dangers, but then again, aren’t we surrounded by various dangers in any case? Though I’m in good health, I might not make next week. A PM group would have the advantage of not being publicly accessible, so not everyone can just wander in—especially those who are vulnerable. Also, it should be clear to everyone joining that they do so at their own risk. For me, such a group wouldn’t be about giving others advice or taking advice from others—but I’d like to hear others’ experience on the path as I find that quite inspiring. Actually, I’d prefer an offline group . . . but we’re all over the world! Finally, I’m mainly in favor of just experimenting with it to see how it goes. If disharmony arises the experiment can be simply abandoned . . .
My paragraph above notwithstanding, I’m sympathetic to your consideration of the dangers of online Dhamma groups. And I don’t want anyone to have negative experiences.
