Chakras: Rays and Radionics

Pretty technical book and I found it to be somewhat useful but a book that is a necessity if one is serious about radionics

Wow, I'm never really sure what David is saying, although part of me senses the truth and is in awe of it. This may sound ridiculous, but that is how I feel. Radionics is real, no question, and David is very controversial obviously (especially within the Radionic community, surprisingly), so it is often like he is speaking an ancient language that is difficult to decipher. His ideas of reading the 7 major rays is fascinating. The reports that he can generate on people are mind blowing. I use various vibrational / energy techniques myself, but what David does and how he thinks is just beyond me currently. It's frustrating, but somehow such an important piece of work. This book is only for very advanced practitioners with an open mind.[...]

if of you are interested in radionics, you should first consider reading from tansley because he is one of the few authors that knows what he's talking about. to delve into this area of spirituality means encountering many persons who will try to influence you to usually buy something that has "magical powers" or try to mislead you to harm towards yourself or others. tansley is definitly not one of them, throughout the book he consistently stresses that radionics is here for personal spiritual growth and not to try anything with out knowledge about the subject. the book is very interesting, and granted you will need to read up much more to understand the bigger pictures of rays, radionics, and chakras, but the book is definitly worth reading as a basic understanding of the three elements.
