Wassily Kandinsky, Piet Mondrian, and other modern artists were
profoundly influenced by this classic of the theosophical tradition,
which explores the concept of what thoughts "look" like. Written by a
pair of prominent theosophists, it provides a way to visualize the
invisible realms within and around us. These simple, clearly expressed,
and well-illustrated discussions address the meaning of color, thought
forms built by music, and related subjects.
British social reformer Annie Besant wrote numerous books and articles
that are still widely considered the best expositions of theosophical
belief. She co-authored this treatise with C. W. Leadbeater, a former
Anglican priest who converted to theosophy. Besant characterized the
purpose of Thought Forms as "as a striking moral lesson to every
reader, making him realize the nature and power of his thoughts, acting
as a stimulus to the noble and a curb to the base."
