I encountered this book as a text for a course on Jewish practices at Spertus Institute of Jewish studies in Chicago. At first glance the simple illustrations and outline seemed too basic to be useful for a serious student. However the discussion of each holiday, both major and minor, provide an extensive explanation of the practices involved in observance of that holiday and the religious principles and philosophy behind each tradition. Also of great help is the margin commentary provided on the text by five different scholars, increasing the breadth and balance of opinion necessary to such a subject. I have found this book of great help in attempting to learn about and return to the faith of my ancestors. I have given my previous copy to a new member of my synagogue who wishes to convert to Judaism and am buying another one for myself.
