Elements & Evolution is a spiritual astrology book for a general audience. It introduces the 4 elements (earth, water, air, fire) and how they interrelate to structure and catalyse evolution. 

This book aims to make several contributions to the field. 

1) New Classification of the Elements: Water & Fire (Charged), Earth & Air (Neutral). 

2) Elemental Levels of Reality Physical (Earth), Emotional (Water), Mental (Air), and Soul (Fire). 

3) In-depth discussion of the evolutionary purpose of every aspect. 

4) Evolution presented cyclically (evolutionary cycle around the zodiac), and progressively (the development of consciousness). 

5) A comprehensive spiritual philosophy of astrology. It is suitable for all astrology students or professionals — anyone who is interested in a spiritual understanding to astrology, and seeks an overarching philosophy of evolutionary growth.
