Take the categories I listed this book under with a grain of salt. It doesn't really seem to fit any of them exactly. That said..
This is a great book which simply and clearly discusses topics to help those who are very sensitive, intuitive and open... or rather Empaths.
The author included (like a medical book), the signs and symptoms, the positive and negative aspects, the remedy as well as the side effects, so to speak.
I love the simplicity and straight forward writing. Well done.
I would recommend.
