The Academy for Spiritual Formation is something that I highly recommend. I am not a graduate of the two-year academy, but I am honored to be a part of a leadership team for the North Texas 5 Day Academy for Spiritual Formation.
It is a joy that the Academy has finally been in a position to catalogue years of lectures on spiritual formation and pull them together in a TEDRadio Hour like podcast. I have listened to all four of them so far. I hope you take time to listen to at least one of them. So far my favorite episodes are #2 and #1. You can find it on iTunes, Soundcloud, or Stitcher.
