I read this book when it was originally published in 2 volumes--however whether it is one or two books is immaterial. If you've read the Seth books you'll love this book!
Seth might appear to some readers to be a bit too intellectual for a formal setting, as I once thought. However, Seth can quite hold his own with some very diverse people, and opinions. This book is basically transcripts from Jane Roberts' ESP class, and the discussion held there.
