This book is not for beginners or newbees(dealing with Psychic Attacks; which is still a rare topic but current event). Ur situation may be advance or frequent, but if you are not into heavy psychic science or raw science in general, then this book needs to be read slow and kept as a reference. TOP NOTCH-EXCELLENT. I was able to follow along after building my studies for 5 yrs. It is known in other science studies, for Practitioners or healers to experience more psychic attacks than the average.
