This is the 19th book in the Loving Heart Centre collection of books about topics of relevance to modern day living. The author in this book sets out the necessary external conditions for a life of perfect love and happiness. By external, he means the outside temperature and the food supply and he sets out his views on what these were like when early human life began on earth. He then discusses the lifestyle of ancient man and woman and how nice this was for the development of perfect love between man and woman. He describes some of the things that went wrong which has led the world to the situation today where love between man and woman is absent. The purpose of the book is to help you understand that modern artificial living is not optimal for you if you wish to develop happiness in your life. And to understand some of the basic ingredients needed if you wish to change to something closer to conditions on earth 50,000 years ago. For example, whether you should remain warm or whether you should brave the cold, and about your diet.
