Here is an excerpt from my book, The Silent Master: Awakening the Power Within:
TAKE CHARGE OF YOUR LIFE
Silent Master Image III
YOUR THOUGHTS CREATE REALITY
Your Silent Master Consciousness knows Itself to be immaterial in substance, but It also takes form (manifests) as your physical body and the material world around you. Thus, you may describe yourself as being both immaterial (spiritual) and material (physical) at the same time.
