A book about oneness 11/26/2023

I read a book written by Julien Chameroy. It was an amazing book talking about the universe and oneness. The book was so attractive that I could not stop putting the book. I ended up keeping the book in my hands until 2 a.m. the author is a French and self-learned Japanese language, so that he wrote down this book almost all by himself. The editor says she corrected 20 % but the majority of 80% was originally written by him.
