Sigma A Guide For True Mental Freedom Provides a new age approach to many old school ways of thought that are lost to society in the 21st century. This guidebook is very opinionated and speaks very plainly about the need to think beyond the current culture and make your own path. This book is simply written and easy to read. By the end of this book the reader will be informed about many of the principles and concepts of the Sigma Philosophy. The reader will be ready to make their own path even if that means not following this philosophy. This is the second edition with corrections.
