Forms of Thought was written by Annie Besant and Charles Leadbeater, first published in 1901. In this unique work, the authors investigate the influence of thoughts and emotions on the creation of colorful forms that can be perceived as separate energy structures. The book examines the phenomenon of synesthesia, when various intellectual and emotional impressions cause the perception of visual images. "Thought Forms" helps the reader understand how thoughts and feelings affect the world around us and our own self-esteem. This book is a valuable resource for those interested in psychology, mysticism, and the interrelationship between the various aspects of our being.
