With respect to Meditation Instruction, my qualifications are a bit unique. I have practiced meditation for over 30 years, primarily in the Buddhist traditions. However, I can teach meditation either within or outside of a spiritual context.
What tends to make a meditation teacher effective are not so much his/her words, as the experiential understanding behind those words. And what generally creates that understanding is the consistent practice of meditation itself . In other words, the mind training that meditation provides. This training of the mind and heart can happen in normal daily life , and it happens especially effectively in silent retreat. I have done countless silent retreats since 1985, and in recent years, for as long as two months at a time.
I have been taught (in and out of retreat) by the most renowned Western teachers of mindfulness and Buddhist Insight Meditation, and in 2017, I was authorized to teach in the Western Tradition of Insight Meditation by these teachers.
