I practice and teach mindfulness meditation, primarily in the shamatha/vipashyana lineage of Shambhala Buddhism. I am trained as Mindfulness Instructor by Naropa University, and currently assist Lama Tenpa Gyaltsen in teaching meditation there.  Lama Tenpa and I are working on a book on meditation together.  I'm publishing it as ablog, and would be very happy to receive your feedback on it.
