Annie Besant
Thought-Forms
"Thought-Forms" by Annie Besant and C. W. Leadbeater is a theosophical book published in 1905. The authors claim to record clairvoyant observations of how thoughts, emotions, and experiences manifest as visible forms in subtle matter. Through color illustrations, they present their system linking specific colors, shapes, and outlines to different mental states—from devotion and love to anger and jealousy. The book argues that thoughts are tangible things that shape both the thinker's experience and influence others around them.
