Hi Yoda.
Amazon reviews can be misleading, theres a lot of hyping and shill reviewing, there may be more in his other ebooks some of them like How to Measure and Deepen Your Spiritual Realization are USD $97 he even peddles one called Meditation for Beautiful Skin anyone here bought any of these ebooks and can give them the thumbs up or down as to whether they have more material in them than the Hua Chin Nan books, ciao, DaChengChuan
