do you have an actual teacher? I have found that the majority of books on chi and chi kungs should be avoided like the plague. Any one who had enough real training and ability to write such a book never would....not because it would be revealing "Secrets" but because they would know there arent any secrets where energy work is concerned. If you train daily use proper breathing and focus your mind on the training while you are doing it, you have all you need...anything else you do is more likely to harm you or at minimum waste your time and money. people can convince themselves of virtually anything...the more you want to believe in it the more likely you are to fool yourself...be careful...find a good teacher and use that book to prop up that wobbly kitchen table, thats where you will likely get the most benifit from it...good luck.
