A list of some very important books that may change your (views on) life:

On past lives and the nature of the universe

Life Between Life (1986)
by Joel L. Whitton, M.D., Ph.D.
A great book with lots of research on Past Life Regression and the nature of our souls. In my view, the best book on Past Life Regression ever written.

The Convoluted Universe - Book Two
by Dolores Cannon
A book that will truly boggle your mind and challenge just about everything you believe in. Fascinating.

On Equality, Society and Politics

Women and Gender In Islam: Historical Roots of a Modern Debate (1992)
by Leila Ahmed
A fantastic book about Islam, gender and culture. It sheds light on a past in a culture that is never analysed from a feminist perspective. This book is one of a kind. It is an essential book for all females rooted in Islamic culture.

The Lucifer Effect - Understanding How Good People Turn Evil (2007)
by Dr. Philip Zimbardo
The title speaks for itself. It is an incredibly important book for anybody who wants to truly understand the nature of humanity, warts and all. It contains reports of psychological experiements and analysis of the abuses at Abu Ghraib.

The Second Sex
by Simone de Beauvoir
This is the most important book on gender equality ever written. It is very old and the language may be difficult if you are reading an English version as it has been a while since it was last translated, but I cannot express how deeply important this book is for understanding what it means to be female in society.

On healing and wellbeing

The Healing Power of Illness: The Meaning of Symptoms and How to Interpret Them
by Thorwald Dethlefsen and Rudiger Dahlke
This book is a great help for understanding your body/soul connection and allows you to heal yourself by getting to the root of your illness. As I am very sceptical of Western medicine and the toxins they often contain, I find the book invaluable. Follow it and you never have to be ill (for long) again!
