I had Peter for the Fiat Lux on Zen Buddhism. It was a really interesting class that I would definitely recommend to anyone vaguely interested. It is very clear that he is passionate about mindfulness, and I believe knowing that about him explains him more as a person. We didn't have homework, except to practice being mindful, and the retreat to a monastery was really an amazing opportunity. Overall, I liked Mr. Kollock; he cares about what he teaches. Just be prepared to see him smile for all class, every class.
