William Walker Atkinson is perhaps one of the most mysterious writers ever to live. He wrote hundreds of books under several different names, transmitting knowledge that was so deep -and so secret-, that you can't help but asking, 'who was this man?'. Even his 'death' is mysterious, as his death certificate is signed by a doctor that has his exact handwriting... In this audiobook Atkinson studies in depth the secrets of the Mind, from Attention, to Memory; from Imagination to Feelings; from Emotions to Passions, from Reasoning to the Training of the Will, giving us a rare insight into our Inner Self, and how it affects our happiness and our whole being.
