I must thank my wife Dr. Adiba K. Shamsi for her total support in my efforts to translate this book. She cheerfully put up with my late hours at the home computer after her long and strenuous day at work, She read the translated manuscript for errors of typography and syntax, so that the readers of this book may enjoy it without the annoying interruptions.

I also thank Br. Nasir Shamsi for carefully screening the contents of the translation for their accuracy and authenticity. His scholarly knowledge of the religious literature has been fully utilized in the preparation of the English book.

Br. Aunali Khalfan gave me valuable technical advice and suggestions for the layout and the final shape of this book. I thank him for his time and assistance.

Syed Haider H. Shamsi, M.D.
