This book is mainly based on the seven Hermetic Principles of Reality and Being which can be employed in order to change one's life conditions and circumstances. These seven Laws of Reality can be found as the essential Principles of all the Western and Eastern spiritual and non spiritual wisdom traditions, and this is the reason why the book also draws many parallelisms with all these traditions and teachings. In final analysis, Truth is always found to be the same whether stated in modern scientific terms or in the language of ancient religion or philosophy, the only difference being in the form of presentation, always bearing in mind that no human formula will ever be able to describe every side of it. Part 1 explains the seven Hermetic Laws or Principles which govern Reality: the Principle of Mind, the Principle of Cause and Effect, the Principle of Vibration, the Principle of Correspondence, the Principle of Polarity (or Opposites), the Principle of Rhythm (or Cyclicity) and the Principle of Gender. Part 2 offers many useful methods that can be employed in order to change one's conditions and circumstances by working with the seven Hermetic Laws of Reality.
