My experience with that is that the attendees know of or attend other mindfulness, or consciousness events, sometimes colloquially called spiritual community. Its a relevant conversation starter to find out where those things are.

There is a parallel lingo and phrasing associated with them, that they gravitate towards if you speak that way.

Its a decent way to begin to see the same people in multiple places, which has a couple of benefits between you and them, as well as others around (or being introduced to others).

And finally, a yoga session is an okay date or social activity to bring someone else to.
