"...symbols are important. They direct, concentrate, discipline, and inform the thought. To be effective, thought must be so motivated and directed... successful performance is directly related to the power of concentration, to the will, to the desire, to total interest and involvement. The person has to be excited; then he can do amazing things... The mind can do astonishing things just by thought. It is a matter of concentrating and ordering it."
Amazing! That quote said it all.
