Never read anything from this author before. I have to say this book is evocative, imaginative, full of ideas (I know authors who could write 10 books with the same ideas) but .. really difficult for me to read. I don't know if it is the style, or just the fact that there's no dialogue in the book: just the author telling the story of his out-of-his-body experience .. a little dry.
The fact that this book was written in the 1930s is also incredible, thinking of what was science fiction back then.
Really recommended, maybe a little at a time.
Also, having read this book in between Iain Banks books, I can't help comparing the two authors. Banks has a fresher style (at least, I can read it more easily), but does not have the same depth of ideas. They both talks about long periods of time, giant evelotionary steps in the history of humans (with the widest definition for 'humans'), they both envision the building of enormous space habitats .. the idea of using planets to travel among galaxies seems a little bit old, but most of the other stuff in this book would not sound wrong in a Banks book.
