This is Jiho, the Rinzai Zen monk heading the temple and retreat.
Not what you might have expected before arriving. He is super playful, not a vegetarian, he drinks beer. When the retreat closes in winter he heads out to Bali and stays at the Hard Rock hotel. He attended probably the toughest temple in Japan for his formation, where many people don't make it through 6 months. He stayed there 5 years. He still comes back there one week a year. But for the rest, he's seen it all, he's past everything. Some things are to be maintained, but at this point he leads a life he really enjoys. It was extremely refreshing.
Playfulness did not exist for the first half of the day though: 5:30 begin with chanting and meditation. After that, service and work in the temple. But as of lunch it was a feast, the most delicious food, fun conversations and socializing. He didn't instruct, he didn't necessarily teach, however I learnt so much.
