There are a whole series of "Seth books", of which The Nature of Personal Reality : Specific, Practical Techniques for Solving Everyday Problems and Enriching the Life You Know (A Seth Book) by Jane Roberts, Robert F. Butts (Contributor) is the first. Whether you order it, or just follow the link without purchasing, you will see a list of the other books in the series and other reader reviews.

The Nature of Personal Reality by Jane Roberts is one of my favorite books of all time. It was published in 1974, but the content is still fresh.

Here a few memorable gems from the book:

"Each thought has a result"

"What exists physically exists first in your thoughts and feeling,
you make your own reality"

"Your environment is the physical picture of your thoughts, emotions, and beliefs
made visible"

"The present is the point of power -- it's where you choose your world and yourself"

I could have included the entire book as a highlight; it's that good and that deep. If you have read Conversations with God or The Seat of the Soul you should notice some similar content, but just realize this book predates those by at least 20 years. --Brother Tom

This book is channelings from "Seth". It is around four hundred pages long. I found it difficult to get into; it was as if I "knew" the message as soon as I leafed through the book, but I just couldn't get past the tone of the writings. I wish Brother Tom would summarize the whole book for me! --JustBetsy
