Teaching focus
Kostura's core teaching draws on mindfulness of breathing, open awareness, noting practice. The frame is the insight tradition transmitted through teachers like Mahasi Sayadaw and U Ba Khin into the West, but the language stays plain. Kostura doesn't lecture from height. The talks tend to think alongside whatever's actually present in the room. Recurring themes include sati, sampajanna, and the three characteristics. None of those get presented as abstract ideas. They're worked into the body, into ethics, into how a practitioner shows up in family life or at work, so that the dharma stops feeling like a separate compartment. There's a steady invitation in the talks to keep practice human-sized. Sit when you can, return when you've drifted, and trust that small consistent attention does more over the years than dramatic breakthroughs. Format-wise, Kostura teaches in in-person, online, and the tone moves easily between guided sittings, dharma talks, and Q&A. Questions tend to get answered the way they were asked, without being reframed into something cleaner. That alone tells you a lot about how the room feels.

He works as an architectural historian, and has published widely in that field. Kostura teaches across several communities, including Insight Meditation Center, Insight Retreat Center. That work sits within the insight tradition transmitted through teachers like Mahasi Sayadaw and U Ba Khin into the West, and the recurring concerns of Kostura's teaching, ethical foundation, steady attention, and the slow softening of habitual reactivity, echo the older texts without sounding distant from a 21st-century practitioner's life. What stands out across Kostura's talks isn't a single technique but a steadying tone. Practice is treated as something built slowly, in ordinary life, with care. There's room for the difficulties practitioners actually bring into the room, grief, restlessness, the body's complaints, family obligations, and the encouragement is consistent without being pushy.
Lineage
Kostura teaches within the insight tradition transmitted through teachers like Mahasi Sayadaw and U Ba Khin into the West. Source notes mention training with Gil Fronsdal. Current affiliations include Insight Meditation Center, Insight Retreat Center. The lineage shows up less in titles than in the way Kostura talks about practice, with steady reference to the older Buddhist vocabulary while keeping the door open for people who've never read a sutra. Whether that framing lands as monastic or lay depends on the specific talk, but the consistent thread is care for the form without letting the form become the point.
What to expect
Sitting with Kostura, you can expect grounded instruction in mindfulness of breathing, with space to ask questions and bring whatever's actually showing up in your practice. Online sessions tend to keep the same shape, shorter sits, a talk, and time for Q&A, in a format that's accessible from home. The teaching voice is steady. Kostura won't push you past your edge, and there's a clear preference for slow, sustainable practice over breakthrough chasing. Bring a notebook if you like, or don't. Either way, you'll be met where you are.
