If you are seeking to better understand the inroads of New Age Spiritualism on Christianity this book is a must read. It is the very best book I have read on the subject. Because it is Scripturally accurate, thoroughly researched, well written and totally understandable, you come away knowing the dangers of some of the spiritual disciplines, such as centering prayer, that are highly recommended by a number of well respected evangelical Christians. Centering prayer can either use a word or phrase (mantra) or focus on the breath as Rick Warren advocates you do in his book, "The Purpose Driven Life." In His chapter on "Discernment' Yungan gives you the facts on everything from the "Chicken Soup For the Soul" books, to Oprah Winfrey, Dr. Phil, the therapeutic modulities of Reikki and Therapeutic Touch and so much more. It saves one the work of having to do all the research for yourself! Yungen also states that he is not interested in slinging mud on names; but rather is challenging Christians to look at the facts surrounding the contemplative prayer movement and other non-biblical practices being embraced by believers, which really blessed me. Many of the inroads of the new age into the Christian church are extremely subtle. As Matthew 24:24 warns us, "For there shall arise false christs, and false prophets, and shall shew great signs and wonders, insomuch that it were possible, they shall deceive the very elect." The only way to keep yourself from falling prey to these many seemingly beneficial practices which are really of the enemy is to inform yourself as to what they are really all about.
