Numerology Books
DIY Numerology
This is a series of books in which I am planning to share my personal experience with numerology. The emphasis of the series is on the practical everyday use of different numerological methods and approaches.
DIY Numerology: Understand Your Past and Discover Your Future in Five Easy Steps

The main topic of this book is the method of Personal Years, which assigns a number to every year of life. Nine years, with numbers from 1 to 9, make a pattern, an epicycle, in which consecutive years can be seen as logical steps on the life's path, or as lessons in the school of life. Personal years are made of personal months and personal days, and these are also discussed in the book. On a bigger scale, the epicycles make a pattern of their own: they form four "pinnacles", and the method of Pinnacles is explained too. Finally, each pinnacle is associated with a "challenge", so a discussion of challenges completes the book.
Recommended Numerology Books
Here I am collecting the books that I found interesting and informative. I am only listing those books that I've read and liked myself.
Numerology: Key to Your Inner Self by Hans Decoz and Tom Monte
Hans Decoz is a well known Master Numerologist whose numerology software generates insightful reports. This book covers all the mainstream methods and tools of numerology, and although it is not as detailed and thorough as the two volumes by Matthew Goodwin (see below), I would wholeheartedly recommend this book to every student of numerology.
The "Other Uses for Numerology" chapter is of a particular interest as it covers topics like ancestral influences, house and telephone numbers, finding lost objects with the help of numbers, the double-digit numbers, and playing with numbers.
Numerology based on Vedic Tradition by Vinod Verma
This book helped me to change my approach to calculating master numbers, and to better understand master numbers. The other calls master numbers 'double numbers', and interprets them as a high intensity version of the number which is repeated. For example, 11 is an intense version of 1, while 22 is an intense version, and so on. This is different from how I used to think about master numbers. In my opinion, 22 is a higher potential hidden in number 4. But after reading this book and thinking about people who have master numbers importantly placed in their numerological profiles, I believe that Vinod Verma's ideas make a lot of sense.
Numerology, the Complete Guide by Matthew Goodwin
This is a massive resource of numerological information. I found this book in a second hand book shop in London many years ago, and it opened my eyes on the rich possibilities offered by Numerology.
The book contains a very well structured, methodical and thorough description of many different numerological parameters, from the Life Path to the Maturity Number and the Secret Self. The book pays a lot of attention to synthesis - a logical interpretation of several different numbers.
If you want to have only one numerology book, I'd recommend this one. But make sure you get Volume 2 as well, it is devoted to numerological prognosis.
The Numerology Kit by Carol Adrienne
A concise, step-by-step practical guide to the main tools of numerology. What makes this book somewhat special is the emphasis on comparing different parameters. For example, there is a section titled "Comparing the Personality to Destiny and Heart's Desire". This is important because once you know a dozen different parameters, you may find it difficult to make sense of them all, especially when they are contradicting one another. It is important to have an understanding of the place and the role of each parameter in the numerological profile, and Carol Adrienne helps the reader to achieve this.
