This book, along with the Edinburgh Lectures will be the only info you need in your library considering Mental Science & the laws of cooperation with the universe. One must keep in mind that the language is NOT modern, Mr. Troward was way ahead of his time over a hundred years ago. If you find contemporary New Thought literature lacking in heart & soul, this information will please you as well as inform you of many important details left out of modern day teachings. Mr Troward, along with other greats such as Ralph Waldo Trine were the inspiration behind many teachers such as Ernest Holmes, Charles Fillmore, etc. Apply what you read here, and you will see a transformation in every area of your life (!). HIGHLY recommended.
