Dinara;
SFQ is Spring Forest Qigong which will make you healthy and raise your energy level. With a high energy level you can perform many things.
"Art of War" is a translated old book based on strategies for overcoming ones enemies. There are many authors out there who have published their rendition. You can find at any book store. It can also be used for peaceful purposes. Knowledge of anything opens it's weaknesses and strengths. Maybe by knowing the situation better, you want to change, it might not need to be changed.
Because of the age of the book, after you have read it, it is good to just take a little quiet time and try to percieve what the orginal author was trying to get across.
Hope this is helpful
