8We may sense that mind plays a critical role in our experience of life, but do we know what mind is, how it functions and what changes might be possible? Revelations of Mind, by Tarthang Tulku and this illuminating new commentary by Richard Dixey open up diverse perspectives for exploring this crucial aspect of our well-being. Searcher Reaches Land's Limits engages the reader in an open, non-dogmatic inquiry that has practical, philosophical, scientific, and meditative dimensions. Touches on current Western understandings of the science of perception, psychology as well as Buddhist thought to inspire the reader to engage in their own journey of self-exploration. This is the first of two commentary volumes. It includes the text of the first half of Revelations of Mind and can be read independently.
