I was looking for information on the Oblates of Wisdom and found this page which may or may not be their official webpage. Their internet presence is sparse enough that I’m not sure.
This page mentions that to be an oblate, you must make a ‘vow of wisdom’. What is that?
I googled “vow of wisdom” and got maybe a dozen responses, most of which were from Buddhist sites. None of the non-Buddhist hits answered your question. Sorry.
