This is a personal account of one man's experiences which helps to relate to the practice of the short form Prof Cheng Man-ching is accredited with creating. If you are serious about taking your practice of the short form to a deeper level, then this book and its sequel Gateway to the Miraculous are necessary to enable you to see what it is all about and where it should take you.
It is a heartfelt commentary rather than an instructional book, but if you are already a student of Taichi with a good teacher, then you will find both books a treasure, which you will relate back to
as you progress. Enjoy!
