As the Former CFO of RJR Nabisco, and Board member of various public and private companies,the Roundabout Theatre Advisory Board, and other organizations and universities, I recommend this book if you're looking for personal and professional success and fulfillment. It not only explains ancient wisdom in non-religious, contemporary, practical terms, it also gives you methods for accomplishment. The techniques in this book work for personal use as well as business.
I have tried reading several Kabbalah books but was usually turned off by too much historical and interlectual information that often required some knowledge of Hebrew. But this book goes right to the core and shows how this ancient spiritual path can be used in today's time and how it is beneficial to anybody - not just people with Jewish background. With all its many excercises I found it very practical and helpful. This is a Kabbalah book that can make a change!
