Volume IV: Further Steps to a Metatranspersonal Philosophy and Psychology: An Assessment of the Transpersonal Paradigms of Grof and Washburn ISBN: 978-1-57733-274-9 Volume IV further discusses the sense of "descending" in the term "descending systems," showing that only systems that are so-in the metaphenomenological, metaexistential sense-agree with Buddhism. It features one Appendix on Greek dualistic philosophical systems, one on psychedelics, and one showing the "participative" perspective not to be inclusive. "This remarkable manuscript presents the Buddhist Dzogchen insights in reader-friendly English that will instruct and inspire its readers. Its importance cannot be underestimated. Indeed, it is destined to become a classic guide to spiritual development." Stanley Krippner, Ph.D., Alan Watts Professor of Psychology, Saybrook University "I can`t pretend to understand all of what Professor Elias Capriles has written in these magnificent four volumes, yet I have the utmost appreciation for the rare combination of impeccable scholarship and lived wisdom that Capriles has shared." Harris L. Friedman, Ph.D., Professor (retired), Professor Emeritus, Saybrook University, Senior Editor, International Journal of Transpersonal Studies "A challenging but exhilarating adventure for any readers interested in existential, humanistic, and/or transpersonal psychologies and their intersection with Dzogchen philosophy and practice." Douglas A. MacDonald, Ph.D., Associate Professor of Psychology, University of Detroit Mercy, Editor Emeritus, International Journal of Transpersonal Studies "These volumes exemplify precisely the direction in which I for one would like to see transpersonal psychology grow: Capriles articulates profoundly innovative ideas about the nature of mind and transformational processes through a solid grasp of the insights from a specific religious tradition." Les Lancaster, Professor Emeritus of Transpersonal Psychology, Liverpool John Moores University, UK. Current President of the International Transpersonal Association.
