The creative use of imagination 

The purpose of this book is to bring about a psychological change in you, the individual. Humanity, understood psychologically, is an infinite series of levels of consciousness and you, individually, are who you are based on where you are in the series. Consciousness is the only reality, and where you are psychologically conscious determines the circumstances of your life. The ancients knew this great truth, but our modern teachers have yet to discover it. There is only one substance in the world. Our scientists call it energy while the scriptures define it as consciousness. We are told that the universe was caused by water, but if this is true, then it could not evolve into anything other than water. But if the basic substance is energy (or consciousness), it can be made to manifest as iron, steel and wood, to name but a few. Man, seeing a variety of forms, thinks of innumerable substances, but what he sees is only a change in the arrangement of the same basic substance: consciousness.
