Query: comprehensive guide for developing one's abilities

I have read a whole bunch of different books for developing psychic ability and while some were very good, this is the best I have encountered so far. I was so impressed with the book I saught the author out for a reading. I received a a phone reading a few days ago, and her information was accurate and VERY helpful for me, which gives me even more faith in following through with the work outlined in the book.I really appreciate how she includes exercises for many practical purposes, such as grounding and clearing out negative energy. I especially like the exercise for Calling Back Your Energy. Even though she is a professional psychic, she actually instructs the readers in detail how they can develop their own abilities and read for others. Now, that's generous!
