This little book is an excellent summary of the book of Dr. Jean Seignalet (power or third medicine). It is a true user guide referencing the large reference manual! It outlines the basic theory behind the principle of Seignalet regime. Then he passes the daily practice of this regime. I think it is interesting to read it before the reference book to understand the intentions of the author Jean Seignalet. Then through referrals, we can deepen a specific subject in the big book. We can also consider it as a beautiful synthesis of the large manual.
