A truth-telling piece of work amongst the lame modern memory books. While the modern memory masters educate artificial methods of memorizing, the author of this book William Walker Atkinson strives on implicating natural(obviously hard) ways to improve our memory. Even though it is an old text, this book gives a simple explanation of our memory system from a different perspective which can’t be defeated by modern discoveries of memory pathways. Worth reading for anybody who desires to improve their memory for anything. Also, it’d be nice to read a modern memory training book and compare both the books to know the greatness of this work .
