What do ideas look like? This clairvoyant view of the shape, color, and atmospheric effect of mental energy includes black-and-white drawings and color plates to convey a graphic representation of the power of thought.
Prominent Theosophists Annie Besant and C. W. Leadbeater were pioneers in asserting that thoughts are, indeed, things.
This book gives you a highly detailed look into thought forms and gives insights on how to deal with them on different levels. As an insight, the clarity and definiteness of the thought form is more important than the strength.
