David Stendl-Rast, a Catholic monk, who had been studying and practicing Buddhist meditation on his own,wanted permission from his superiors to study with a Buddhist monk/teacher. 

The superiors invited the teacher to spend some time in the monastery and requested to interview him at the end of his stay.

The teacher lived at the monastery for several days working, living and practicing with the Catholic monks. At the end of his stay the superiors interviewed the Buddhist teacher.

After the interview the superiors talked with Stendl-Rast.  They  said that the Buddhist teacher’s answers to their questions made no sense to them, but they could see by the way he lived that he was a deeply spiritual person.

They gave permission for Stendl-Rast to study and practice with him.
