I really think exposure is important.....the availability, for instance of Rohr's Falling Upward was of sufficient concern to a local pastor that he had a lot of copies available for sale .....at the rectory.

I once lived in a parish that did "prayer Clinics" and taught folks the basics of Centering prayer, lectio divina, a bit about the Ignatian Exercises etc AND had a lot of books available...for everyone's use...

I think that it so often depends on the pastor....a real prayerful guy may well be open to these things...an autocrat, not so much.

I also think that if there are volunteers and donations it really helps promote such endeavors...
