She was teaching in the late 1800's what the mindset gurus are teaching now. I discovered her about 20 years ago, and have been a delighted student of her work since. I have multiple copies of everything she wrote, so that I can lend them out. Two you may have heard of are "The Game of Life and How To Play It" and "Your Word is Your Wand". This little treasure is called "The Magic Path of Intuition" which is really about learning to hear and follow that still small voice.
Here's a photo of the cover of this lovely little book.
