In this book the authors demonstrate that they know a lot about the conservation and circulation of male sexual energy. In a very detailed manner they explain the techniques to circulate the sexual energy in the male body. Moreover, they convince the reader strongly of the benefits of conserving and circulating the sexual energy in the male body.
However, they fail to mention the dangers of some of these practices - in particular the dangers of the power lock method (or 'big draw') that is described in this book and works with hot, male sexual energy. They assume uncarefully that the reader knows the basics of the Taoist system and/or is already aware of these dangers (as they were mentioned in ‘Awaken healing energy through the tao’, an earlier book from Mantak Chia). But in this way the authors forget to include some very important warnings in the book: 1) This book contains advanced, powerful energetic practices of the Taoist system. Don’t do these exercises when you have not mastered the basics. 2) Don’t do these exercises without the guidance of a senior Taoist instructor. 3) Read the other book ‘Awaken healing energy through the tao’ first if you would be considering to try these practices.
If you are a man or a boy and you found this book because you are interested in sexuality but don’t know anything about Taoism, don’t do these practices before you learn more about Taoism first. The male sexual energy that is circulated can be very powerful. When the sexual energy is circulated and gets stuck in the body (especially the head), these practices can lead to mental illness such as depression or psychosis, physical diseases unexplainable by Western science, or have other side-effects such as headaches.
I would recommend to not do these practices (to circulate your sexual energy) at all. There are many dangers to these practices and you don't need to do them at all to live a happy and healthy life. Nevertheless, understanding and applying the great benefits of conserving (in contrast to circulating) your sexual energy is very important and can improve your quality of life enormously, which is described correctly by the authors. Conserving your sexual energy properly can give you more energy, improve your physical and mental health, strengthen your relationships and make you calmer, stronger, more masculine and more confident.
