Great series!
We've discussed Fr. Seraphim's podcasts on here before. Have you listened to the ones on Confession? The ones on prayer ARE very good, but I think those are even better.
He's one of my favorite podcasters. I usually listen to his at least 3x to get all I can out of them. He's also pretty insightful and good at answering email, though I know he's terribly busy with fundraising for the monastery, working on the Church, and right now leading a pilgrimage group. I've had one or two difficult questions on prayer that weren't finding answers elsewhere, and he doesn't mind telling it like it is. I've felt chastised a bit, but very grateful for it. I only wish I knew him well in person, instead of just through FB and email.
I don't think he wants the job, but if he ever becomes an Abbott, I think he will be a good one.
