Dan Brown has thoroughly investigated and experimented with the enormous literature and tradition derived from these thousands of years of codified experience, collected in the Indian and Tibetan scientific and psychological literature. To this he has added comprehensive research and insightful understanding of contemporary depth, behavioral, cognitive, and the newly nascent meditational, psychologies, which enable him to transmit the tradition in language accessible to any practitioner without access to the primary sources. Finally, he speaks not only as a scholar and an external scientist, but also as an inner scientist, a yogin of knowledge and experience, as he has practiced these paths in his own mind, with his own body, and so can make clear the discoveries that texts of observation can only describe, while manuals of practice must evoke, to help us to embody them in realization ourselves.
